Constant Voltage Control Block (REG2) This constant voltage control block (REG2) uses voltage supplied from reference voltage generates output voltage (1.8 from OUT2 terminal (pin 30). external load current obtained from OUT2 terminal maximum Also, setting ICONT terminal (pin level MB3893A placed current consumption (standby) mode. standby mode, REG2 with maximum output load REG3 Off. this state, ripple rejection noise levels assured. Constant Voltage Control Block (REG3) This constant voltage control block (REG3) uses voltage supplied from reference voltage generates output voltage from OUT3 terminal (pin 27). external load current obtained from OUT3 terminal maximum Also, output voltage changed 1.9V mask option. Constant Voltage Control Block (REG4) This constant voltage control block (REG4) uses voltage supplied from reference voltage generates output voltage (2.5 from OUT4 terminal (pin 22). external load current obtained from OUT4 terminal maximum Also, setting ICONT terminal (pin level MB3893A placed current consumption (standby) mode. standby mode, REG4 with maximum output load REG3 Off. this state, ripple rejection noise levels assured. VREF1M This block takes reference voltage (1.23 (Typ.)) generated reference voltage block, uses voltage follower produce temperature compensated reference voltage (1.23 (Typ.)) VREF1M terminal (pin 10). Also, external load current obtained from VREF1M terminal maximum ON/OFF Control Block This block controls regulator On/Off switching according voltage levels POFF terminal (pin 18), CONT2 terminal (pin 26), CONT5 terminal (pin ICONT terminal (pin 36), DRST terminal (pin terminal (pin 11), ONOFF1 terminal (pin ONOFF2 terminal (pin 17), CONT1 terminal (pin 14).
MB3893A
Block When output voltage from regulator (OUT1) exceeds (Typ.), XRST terminal (pin goes level following delay time (Typ.)) capacitors (0.1 (Typ.)) connected between terminal (pin GND1 terminal (pin GND2 terminal (pin 39). Also, when regulator (OUT1) output voltage falls below ((Typ.)), XRST terminal goes back level. Initial Power Supply Drop Detection This block controls MB3893A operation when startup occurs voltage 2.0V (Typ.) greater. When voltage exceeds 2.75V (Typ.) VCONT terminal (pin voltage goes level, regulated voltage output from OUT1 terminal (pin 29), OUT2 terminal (pin 30), OUT4 terminal (pin 22). When voltage falls below 3.1V (Typ.), voltage OUT1, OUT2, OUT4 terminals outside rated values. Then when voltage falls below 2.5V (Typ.), VCONT terminal (pin voltage goes level, OUT1, OUT2, OUT4 terminals level (regulator "OFF" state). Hereafter this referred level. long voltage rises again before dropping below 2.0V (Typ.), VCONT voltage will return level once reaches (Typ.), regulated voltage output from OUT1, OUT2, OUT4 terminals. (10) Transient Power Supply Drop Detection This block detects types power supply drop times according time constants CR2, produces related output VBDET1 terminal (pin VBDET2 terminal (pin 33).
Charge Control Block
charge control block checks VIN, battery voltage, battery temperature before charging. results within normal ranges, charging begins. During charging, charging times current levels varied according battery voltage. battery temperature monitored, either exceeds normal range charging stopped. Conditions then monitored fixed time (Typ.)) resume charging/ abnormal termination determination made. MB3893A also provides overcharge protection function, well function that stops charging when rise junction temperature detected. Once charging stopped these abnormal conditions, resumed re-input VIN, removing replacing battery. Constant Current/Constant Voltage Charging MB3893A applies constant current charge according battery voltage level, selecting over discharge recovery charging (2.1 (Typ.)), preliminary charging (Typ.)) rapid charging (590 (Typ.)). Once battery voltage reaches (4.2 constant voltage charging applied until charge current falls (Typ.) constant voltage. Timer Function timer switches charging time according battery voltage level, between over discharge recovery charging (Typ.)), preliminary charging (Typ.)), rapid charging (240 (Typ.)). Temperature/AC Adapter Voltage Detection This block detects battery temperature adapter voltage, stops charging either outside normal charging range. normal conditions restored within time (Typ.)), charging resumed, otherwise abnormal termination determined. Over-Charge Protection battery voltage exceeds (Typ.) this block determines abnormal condition, stops charging.

After delay interval (tXON 600ms (Typ.)), once terminal exceeds internal threshold voltage VCONT terminal (pin goes level, OUT1 (pin 29), OUT2 (pin 30), OUT3 (pin 27), OUT4 (pin terminals then output their respective regulated voltages after delay interval (tR1). Note however that OUT3 terminal output regulated voltage, necessary CONT2 terminal (pin level. Also, return from level level, delay interval (tXON (Typ.)) required.

USAGE PRECAUTIONS
Never settings exceeding maximum rated conditions.
Exceeding maximum rated conditions cause permanent damage LSI. Also, recommended that recommended operating conditions observed normal use. Exceeding recommended operating conditions adversely affect reliability.
this device within recommended operating conditions.
Recommended operating conditions values within which normal operation warranted. Standard electrical characteristics warranted within range recommended operating conditions within listed conditions each parameter.
Printed circuit board ground lines should with consideration common impedance. Take appropriate static electricity measures.
Containers semiconductor materials should have anti-static protection made conductive material. After mounting, printed circuit boards should stored shipped conductive bags containers. Work platforms, tools, instruments should properly grounded. Working personal should grounded with resistance between body ground.
apply negative voltages.
negative voltages below -0.3 create parasitic transistors lines, which cause abnormal operation.
