Description

The ISL9212IRZ belongs to ISL9212, which is an integrated circuit (IC) optimized to provide a Li-ion battery redundant safety protection from failures of a charging system. The IC monitors the input voltage, the battery voltage, and the charge current. When any of the three parameters exceeds its limit, the IC turns off an internal P-channel MOSFET to remove the power from the charging system. In addition to the above protected parameters, the IC also monitors its own internal temperature and turns off the P-channel MOSFET when the die temperature exceeds 140°C. Together with the battery charger IC and the protection module in a battery pack, the charging system using the ISL9212 has triple-level protection and is two-fault tolerant. The IC is designed to turn on the internal PFET slowly to avoid inrush current at power-up but will turn off the PFET quickly when input overvoltage is detected, in order to remove the power before any damage occurs. The ISL9212 has a logic warning output to indicate the fault and an enable input to allow the system to remove the input power.

The features of ISL9212 can be summarized as (1)fully integrated protection circuit for three protection variables: user programmable overcurrent protection threshold; input overvoltage protection in less than 1 s; battery overvoltage protection; (2)high immunity of false triggering under transients; (3)high accuracy protection thresholds; (4)warning output to indicate the occurrence of faults; (5)enable input; (6)thermal enhanced DFN package; (7)pb-free plus anneal available (rohs compliant) It can be applicated incell phones
; digital still cameras; PDAs and smart phones; portable instruments; desktop chargers.

The maximum absolute ratings of ISL9212 are(1)supply voltage (VIN):-0.3 to 30V; (2)output and VB pin (OUT, VB) (Note 1: The maximum voltage rating for the VB pin under continuous operating conditions is 5.5V. All other pins are allowed to operate continuously at ; (3)the absolute maximum ratings.): -0.3 to 7V; (4)other pins (ILIM, WRN, EN) :-0.3 to 5.5V; (5)ambient temperature range:-40°C to 85°C; (6)supply voltage, VIN:4.3V to 6.5V; (7)operating current range:0A to 1.5A; (8)maximum junction temperature(plastic package): 150°C; (9)maximum storage temperature range: -65°C to 150°C; (10)maximum lead temperature (soldering 10s): 300°C(CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.)
