Nisshinbo Micro Devices R5601T063AA-E2-FELow Side, Low Side Power Control Switch 16-Pin, TSSOP-16

The Nisshinbo Micro Devices Battery Management IC is designed for use with a microcontroller and features and analog front end with overcurrent protection for multi cell Li ion or Li polymer battery packs. It supports battery packs consisting of up to 5 cells in series. It provides a cell selection switch, a decoder that selects the cell to be monitored based on input signals from external devices, an amplifier that outputs the monitored battery voltage, an additional amplifier that monitors charge and discharge currents based on the voltage at both ends of external resistors and then converts the current values to voltage and outputs the voltage values.

Provides a low current voltage regulator that provides voltage to the MCU
Provides a thermal shutdown circuit
Provides an alert output pin that notifies external devices of any errors
