TPS3840 - High Input Voltage Supervisor

Description

Wide Vin allows monitoring 9V rails or batteries without external components and 24V rails with external resistors.

Nano-Iq extends battery life for low power applications and minimizes current consumption when using external resistors.

Features

  • 1 Wide operating voltage: 1.5 V to 10 V.
  • Nano supply current: 300 nA (Typ), 700 nA (Max).
  • Fixed threshold voltage (VIT-).
  • Threshold from 1.6 V to 4.9 V in 0.1-V steps.
  • High accuracy: 1% (Typ), 1.5% (Max).
  • Built-in hysteresis (VIT+).
  • 1.6 V < VIT- ≤ 3.0 V = 100 mV (Typical).
  • 3.1 V ≤ VIT- < 4.9 V = 200 mV (Typical).
  • Start-up delay (tSTRT): 220 µs (Typ), 350 µs (Max).
  • Programmable reset time delay (tD):.
