SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH WITH OUTPUT DISCHARGE Application Note
AP2161D AP2171D integrated high-side power switches optimized Universal Serial (USB) that requires protection functions. power switches equipped with driver that controls gate voltage incorporates slew-rate limitation. This, along with various protection features special functions, makes these power switches ideal hot-swap hot-plug applications.
Protection Features: Under-voltage Lockout (UVLO)
Under-voltage lockout function (UVLO) guarantees that internal power switch initially during start-up. UVLO functions only when switch enabled. Even switch enabled, switch turned until power supply reached least 1.9V. Whenever input voltage falls below approximately 1.9V, power switch turned off. This facilitates design hot-insertion systems where possible turn power switch before input power removed.
PRODUCT
Over-current Short Circuit Protection
internal sensing employed check over-current conditions. Unlike current-sense resistors, sense FETs increase series resistance current path. When over-current condition detected, device maintains constant output current reduces output voltage accordingly. Complete shutdown occurs only fault stays long enough activate thermal limiting. different overload conditions corresponding response AP2161D/2171D outlined below: S.NO Conditions Short circuit condition start-up Explanation Output shorted before input voltage applied before part enabled Short-Circuit Overload condition that occurs when part enabled. Behavior AP2161D/2171D senses short circuit immediately clamps output current certain safe level namely ILIMIT. instance overload occurs, higher current flow very short period time before current limit function react. After current limit function tripped (reached over-current trip threshold), device switches into current limiting mode current clamped ILIMIT. current rises until ITRIG thermal limit. Once threshold been reached, device switches into current limiting mode ILIMIT.
Short-circuit overcurrent condition
Gradual increase from nominal operating current ILIMIT
Load increases gradually until current-limit threshold.(ITRIG)
Note that when output been shorted extremely temperature -30oC), minimum 120-F electrolytic capacitor output recommended. correct capacitor type with capacitor voltage rating temperature characteristics must properly chosen that capacitance value does drop extremely temperature operation. recommended capacitor should have temperature characteristics less than variation capacitance change when operated extremely temp. recommended aluminum electrolytic capacitor type Panasonic series.

SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH WITH OUTPUT DISCHARGE Application Note (Continued)
Thermal Protection
Thermal protection prevents from damage when temperature exceeds safe margins. This mainly occurs when heavy-overload short-circuit faults present extended periods time. AP2161D/AP2171D implements thermal sensing monitor operating junction temperature power distribution switch. Once temperature rises approximately 140°C, Thermal protection feature gets activated follows: internal thermal sense circuitry turns power switch output asserted thus preventing power switch from damage. Hysteresis thermal sense circuit allows device cool down approximately 25°C before output turned back This built-in thermal hysteresis feature excellent feature, avoids undesirable oscillations thermal protection circuit. switch continues cycle this manner until load fault removed, resulting pulsed output. open-drain output asserted when over-current occurs with 7-ms deglitch.
PRODUCT
Reverse Current Protection
normal MOSFET switch, current flow reverse direction (from output side input side) when output side voltage higher than input side, even when switch turned off. reverse-current blocking feature implemented AP21x1 series prevent such back currents. This circuit activated difference between output voltage input voltage. When switch disabled, this feature blocks reverse current flow from output back input.
Special Functions: Discharge Function
When enable de-asserted, discharge function active. output capacitor discharged through internal NMOS that discharge resistance 100. Hence, output voltage drops down zero. time taken discharge dependent time constant resistance output capacitor.
Response
open-drain output goes active conditions: Over-Current Over-Temperature. time from when fault condition encountered when output goes 7-ms (TYP). output remains until both over-current over-temperature conditions removed. Connecting heavy capacitive load output device cause momentary Over-current condition, which does trigger 7-ms deglitch timeout. This 7-ms timeout also applicable Over-current recovery Thermal recovery. AP2161D/AP2171D designed eliminate erroneous Over-current reporting without need external components, such delay network.
Applications Information: Power Supply Considerations
0.01-F 0.1-F ceramic bypass capacitor between GND, close device, recommended. This limits input voltage drop during line transients. Placing high-value electrolytic capacitor input (10-F minimum) output pin(s) recommended when output load heavy. This precaution also reduces power-supply transients that cause ringing input. Additionally, bypassing output with 0.01-F 0.1-F ceramic capacitor improves immunity device short-circuit transients. This capacitor also prevents output from going negative during turn-off inductive parasitics.

Generic Hot-Plug Applications
many applications necessary remove modules boards while main unit still operating. These considered hot-plug applications. Such implementations require control current surges seen main power supply card being inserted. most effective control these surges limit slowly ramp current voltage being applied card, similar which power supply normally turns controlled rise times fall times AP2161D/AP2171D, these devices used provide softer start-up devices being hot-plugged into powered system. UVLO feature AP2161D/AP2171D also ensures that switch after card been removed, that switch during next insertion. placing AP2161D/AP2171D between input rest circuitry, input power reaches these devices first after insertion. typical rise time switch approximately 1ms, providing slow voltage ramp output device. This implementation controls system surge current provides hotplugging mechanism device.
