Introduction

AI Translation

Wide operating voltage range: 1.5V to 10V Nano-power supply current: 300nA (typical), 700nA (maximum) Fixed threshold voltage (VIT-) threshold range: 1.6V to 4.9V (in 0.1V steps) High accuracy: 1% (typical), 1.5% (maximum) Built-in hysteresis (VIT+): 1.6V < VIT ≤ 3.0V = 100mV (typical), 3.1V ≤ VIT < 4.9V = 200mV (typical) Fast startup delay (tSTR T): 220μs (typical), 350μs (maximum) Programmable reset delay time (tD): 50μs (no capacitor) to 6.2s (10μF) Active-low manual reset (MR(overline)) Three output topologies:

  • TPS3840DL: open-drain, active-low (RESET), requires pull-up resistor
  • TPS3840PL: push-pull, active-low (RESET)
  • TPS3840PH: push-pull, active-high (RESET)

Wide temperature range: -40°C to +125°C Package: SOT23-5 (DBV)
