R5602 Series
4-Cell to 7-Cell Li-ion Battery Management Analog Front-End IC
-
Description
The R5602 is an analog front-end IC for 4-cell to 7-cell Li-ion / Li-polymer battery management. This IC provides cell voltage monitor, bidirectional current monitor based-on monitoring the voltage across an external sense resistor, two input pin for temperature monitoring by external NTC thermistors, Die temperature monitor, overcurrent protection, high-side NMOSFET control, a voltage regulator, cell balancing switches, switch for open-wire detection and I2C/SPI interface. The IC has a built-in A/D converter and an MCU can read each monitor value as a digital value.
Key Benefits
- High accuracy voltage monitoring and low power consumption - for saving battery life.
- Control High-side NMOSFET - for ease of treatment and cost reduction of BOM.
- Cell connection sequence free - for cost reduction of battery pack assembling.
