Product Summary

The ISL9204IRZ-T is a cost-effective, fully integrated high input voltage single-cell Li-ion battery charger. The ISL9204IRZ-T performs the CC/CV charge function required by Li-ion batteries. The ISL9204IRZ-T accepts an input voltage up to 28V but is disabled when the input voltage exceeds the OVP threshold, minimum 10V, to prevent excessive power dissipation. The 28V rating eliminates the overvoltage protection circuit required in a low input voltage charger. Applications are (1)Mobile Phones; (2)Blue-Tooth Devices; (3)PDAs; (4)MP3 Players; (5)Stand-alone Chargers; (6)Other Handheld Devices.

Parametrics

ISL9204IRZ-T absolute maximum ratings: (1)VIN: -0.3V to 30V; (2)IMIN, IREF, BAT, CHG, EN, PPR: -0.3V to 7V; (3)Ambient Temperature Range: -40°C to 85°C; (4)Maximum Supply Voltage (VIN Pin): 28V; (5)Operating Supply Voltage (VIN Pin): 4.3V to 10V; (6)Programmed Charge Current: 50mA to 350mA.

Features

ISL9204IRZ-T features: (1)Complete Charger for Single-Cell Li-ion/Polymer Batteries; (2)Integrated Pass Element and Current Sensor; (3)No External Blocking Diode Required; (4)Low Component Count and Cost; (5)1% Voltage Accuracy; (6)Programmable Charge Current; (7)Programmable End-of-Charge Current; (8)Charge Current Thermal Foldback for Thermal Protection; (9)Trickle Charge for Fully Discharged Batteries; (10)28V Maximum Voltage for the Power Input.
