ZSPM4121
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 500m V above the set voltage threshold, the load switch turns on and connects the battery to the load. The 500m V 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 4.2V in 100m V increments to support a wide range of applications in consumer, medical, portable, and industrial applications.
This device has ultra-low quiescent current, which makes it ideal for battery-powered applications. Typical quiescent current is 100p A in the Off Mode and 70n A in the On Mode.
The ZSPM4121 includes a slew rate control P-channel load switch, over-current...
