RICHO R5601T
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.
