ZSPM4121
ZSPM4121 is Under-Voltage Load Switch manufactured by Renesas.
Under-Voltage Load Switch for Smart Battery Management
Brief Description
The ZSPM4121 battery management load switch can be used to protect a battery from excessive discharge. It actively monitors the battery voltage and disconnects the battery from the load if the battery drops below a set voltage threshold. When the input battery voltage reaches 500mV above the set voltage threshold, the load switch turns on and connects the battery to the load. The 500mV hysteresis between the Off Mode and the On Mode prevents intermittent operation.
The voltage threshold (VTHRESH) can be programmed at manufacturing to a customer-selected set point in the voltage range of 1.2V to...
