ZSPM4121 Under-Voltage Load Switch for Smart Battery Management Datasheet Brief Description Features The ZSPM4121 battery management load switch Threshold voltage options of 1.2V to 4.2V in can be used to protect a battery from excessive 100mV steps (factory programmed) discharge. It actively monitors the battery voltage Wide input voltage range: 1.2V to 5.5V and disconnects the battery from the load if the Supervisory over-current limit shutdown: (3A) battery drops below a set voltage threshold. When Low drop-out disconnect from VCC to loads the input battery voltage reaches 500mV above the Controlled turn-on slew rate set voltage threshold, the load switch turns on and 500mV Off Mode to On Mode hysteresis connects the battery to the load. The 500mV hysteresis between the Off Mode and the On Mode prevents intermittent operation.

Evaluation Kit This device has ultra-low quiescent current, which Support Documentation makes it ideal for battery-powered applications. Typical quiescent current is 100pA in the Off Mode and 70nA in the On Mode. Physical Characteristics The ZSPM4121 includes a slew rate control P-chan- Package: 8-pin DFN (2mm x 2mm) nel load switch, over-current protection, and an open-drain power indicator pin (NPG). The slew-rate controlled turn-on characteristic prevents inrush current and voltage droop on the voltage. The over- ZSPM4121 Block Diagram current limit protects the device in case of an overload, short-circuit, or ground fault event.
