ZSPM4121 - Under-Voltage Load Switch

General 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.

Key Features

  • Threshold voltage options of 1.2V to 4.2V in 100mV steps (factory programmed).
  • Wide input voltage range: 1.2V to 5.5V.
  • Supervisory over-current limit shutdown: (3A).
  • Low drop-out disconnect from VCC to loads.
  • Controlled turn-on slew rate.
  • 500mV Off Mode to On Mode hysteresis Related IDT Smart Power Products.
  • ZSPM4141 Ultra-Low-Power Linear Regulator Available Support.
  • Evaluation Kit.
  • Support Documentation Physical.

Under-Voltage Load Switch for Smart Battery Management ZSPM4121 Datasheet 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 4.
