R5601T Series
Lithium-Ion/ Lithium Polymer Battery Management Analog Front-End
NO.EA-356-190910
OVERVIEW
The R5601T is a battery management IC designed for use with a microcontroller and features and analog front-end with overcurrent protection for multi-cell Li-ion/ Li-polymer battery packs. The R5601T supports battery packs consisting of up to 5 cells in series. The R5601T 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, a low-current
voltage regulator that provides
voltage to the MCU, a thermal shutdown circuit, an alert output pin that notifies external devices of any errors, and various logic circuits. The R5601T is offered in a 16-pin TSSOP-16 package.
