PT7M7433TAEX

Diodes Incorporated · Monitors & Reset Circuits · SOT-23-5

PT7M7433TAEX from Diodes Incorporated, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 HTHIN input HTH threshold monitor input; a resistor-divider network sets the high threshold (615mV internal reference) associated with LBO/LBO.
2 GND power_in Ground reference pin for the device.
3 LTHIN input LTH threshold monitor input; a resistor-divider network sets the low threshold, and LBO is asserted when LTHIN falls below 615mV.
4 LBO output Low-battery output, asserted when LTHIN drops below VLTHIN and kept asserted for at least 90ms after HTHIN rises above VHTHIN; push-pull output for PT7M7433.
5 VCC power_in Supply voltage pin providing device power for the adjustable threshold versions, with an operating voltage range of 1.8V to 5.5V.

CAD (KiCad official)

  • Symbol: PT7M7433TAEX
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: pt7m7433taex-etched.step / pt7m7433taex-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pt7m7433taex.step / pt7m7433taex.glb are the bare package body.
