Nexperia Battery Life Booster IC

Battery Life Booster IC – Extend coin cell battery life and optimize peak current for pulse load

The NPS4053 switch limits the output current to a constant current by using a constant-current mode when the output load exceeds the current limit threshold or shorted. An internal voltage comparator disables the load switch when the output voltage is higher than the input to protect devices on the input side of the switch. The FLG pin is an active low output to indicate overcurrent, over temperature and reverse voltage conditions.

Features & benefits

  • Programmable constant battery load current: 2 mA to 16 mA
  • Protection against battery voltage dips (Brown-out)
  • Pulse output current: 150 mA
  • Regulated programmable output voltage: 1.8 V to 3.6 V
  • Low output voltage ripple
  • Ultra-low standby current: < 20 nA
  • Typical conversion efficiency of 90% with adaptive optimization
  • Integrated fuel gauge
  • Integrated balancing circuit
  • One auxiliary regulated output pin
  • Small 16 pin lead-free package (SOT763-1/DHVQFN16; 2.5 mm × 3.5 mm × 0.85 mm)
  • Specified from -40 °C to +85 °C
