ZMDI ZSPM4121 Battery Management Load Switch

ZMDI ZSPM4121 Battery Management Load Switch

ZMDI's ZSPM4121 Battery Management Load Switch can be used to protect a battery from excessive discharge. It actively switches the battery power source off if it drops to a set threshold (Off Mode). When the input battery voltage is above the threshold, the load switch is on (On Mode). The ZSPM4121 threshold voltage (VTHRESH) is programmed at manufacturing to a set point in the range of 1.2V to 4.2V with 100mV steps between options. When the input battery voltage has been switched off by the ZSPM4121, the quiescent current draw on the battery is in the order of 100pA (typical). The ZSPM4121 consists of an internally generated threshold voltage, a comparator with hysteresis, slew rate control for the load switch, a P-channel load switch, and an open-drain indicator pin.

Features
  • Power source is actively switched off when VCC drops below a set threshold (programmed at manufacturing)
  • Wide input voltage range: 1.2V to 5.5V
  • Threshold voltage options of 1.2V to 4.2V in 100mV steps (factory programmed)
  • Supervisory over-current limit shutdown
  • Low drop-out disconnect from VCC to loads
  • Controlled turn-on slew rate
  • 500mV Off Mode to On Mode hysteresis
  • Over-current shutdown (3A)
  • Best-in-class ultra-low quiescent current in Off Mode: 100pA (typical)

  • Ultra-low quiescent current in On Mode: 70nA (typical)
  • Accurate on/off voltage threshold
  • Low Rds(on): 175mΩ (typical) @ 5V

Applications
  • Portable Batteries
  • Industrial
  • Medical
  • Smart cards
  • RFID
