IMP812MEUS-T overview
IMP812MEUS-T is a component documented by IMP, Inc. The PDF description identifies it as "4-pin 關P Voltage Supervisor with Manual Reset." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- reset pulse width N Guaranteed over temperature N Active-LOW reset valid with 1.1V supply (IMP811) N Small 4-pin SOT-143 package N No external components N Power-supply transient-immune design Block Diagrams IMP811 (IMP812) VCC VCC VCC GND.
- The IMP811/812 are improved drop-in replacements for the Maxim MAX811/812 with extended temperature specifications to 105°C.
- A reset signal is issued if the power supply voltage drops below a preset threshold and is asserted for at least 140ms after the supply has risen above the reset threshold.
- The IMP811 has an active-low output RESET that is guaranteed to be in the correct state for V CC down to 1.1V .
- Coefficient TC VTH 30 ppm/°C VCC to Reset Delay V CC = VTH to (VTH - 125mV), L/M/J devices 40 µs VCC = VTH to (VTH - 125mV), R/S/T devices 20 Reset Active Timeout Period T A = 0°C to 70°C 140 560 ms TA = –40°C to 105°C 100 840 MR Minimum P.
- Typical values at TA = 25°C, VCC = 5V for L/M/J devices, VCC = 3.3V for T/S devices and VCC = 3V for R devices.
- Production testing done at T A = 25°C.

Engineering review checklist
- Confirm supply rails, clock limits, memory size, peripheral mapping and I/O voltage compatibility.
- Check package pinout, boot configuration, programming interface and silicon-revision errata.
- Budget decoupling, thermal margin, startup timing and firmware recovery behavior before release.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
