概要

Description

The IMP811SEUS/T is a microprocessor supervisory circuit designed to monitor system power supplies and ensure proper operation. Key features include:
- Voltage Monitoring: Tracks VCC (1.8V to 5V) and asserts a reset signal if voltage drops below a preset threshold.
- Manual Reset Input: Allows external reset triggering via a push-button.
- Reset Output: Active-low or active-high (depending on variant) to control system reset.
- Low Power Consumption: Ideal for battery-powered applications.
- Compact Package: Available in SOT-23 or similar small form factors.
Commonly used in embedded systems, industrial controls, and consumer electronics, the IMP811SEUS/T enhances system reliability by preventing erratic behavior during power fluctuations.
For detailed specs, refer to the datasheet.

Features

The IMP811SEUS/T is a microprocessor supervisory circuit with the following key features:
- Voltage Monitoring: Monitors 3V, 3.3V, or 5V systems.
- Manual Reset Input: Allows external reset triggering.
- Reset Output: Active-low (RESET) or active-high (RESET) options.
- Reset Timeout: Fixed 140ms delay after voltage stabilization.
- Low Power Consumption: Typically 5µA in standby.
- Wide Operating Voltage: 1.2V to 5.5V.
- Temperature Range: -40°C to +85°C.
- Package: SOT-23-5.
Ideal for ensuring reliable system operation in embedded applications.

Pinout

The IMP811SEUS/T is a microprocessor supervisory circuit in a SOT-143 package with 4 pins. Its key functions are:
1. Reset Output – Asserts a reset signal when VCC drops below a preset threshold (typically 4.63V for IMP811).
2. Manual Reset Input – Allows an external push-button to trigger a reset.
3. Power Monitoring – Monitors VCC and holds the reset signal until voltage stabilizes.
4. Debounced Reset – Ensures a clean reset pulse (~140ms minimum).
Pins:
- VCC (Pin 1) – Power supply input.
- GND (Pin 2) – Ground.
- RESET (Pin 3) – Active-low reset output.
- MR (Pin 4) – Manual reset input (active-low).
It’s commonly used in embedded systems to ensure proper startup and recovery.
