Overview

Description

MIC809-5SYC3-TR is a member of Microchip/Micrel’s MIC809 family: a fixed-delay, one-shot timing device. It generates a precise, single output pulse after power-up or when triggered, making it ideal for microcontroller reset, debouncing, or timing delays with minimal external components. It is a low-power, single-supply device (typical operation in a few volts) with CMOS/TTL-compatible outputs. The suffix -TR indicates Tape & Reel packaging, while -5SYC3 encodes the timing/variant and package code (specifics appear in the datasheet). Applications include power-on reset, timing generation, and pulse stretching in compact, battery-powered circuits. For exact timing range, voltage supply, pinout, and electrical characteristics, refer to the MIC809 datasheet and the exact variant specification.

Features

Here are the typical features for MIC809-5SYC3-TR (voltage supervisor/reset IC):
- Fixed 5.0 V reset threshold
- Power-on reset guarantees a defined reset during power-up/power-down
- Reset output suitable for MCU supervision
- Low quiescent current (very small idle current)
- Small package footprint (SC-70/SOT-23-6 family) with Tape & Reel packaging (TR)
- Industrial temperature range (typical for harsh environments)
- Designed for reliable brown-out/reset protection in microcontroller-based systems
Note: For exact electrical specs (delay, drive strength, input/output conditions) refer to the official datasheet.

Package

5‑pin SOT‑23 (SOT‑23‑5/SC‑70‑5) package, shipped in Tape‑and‑Reel (TR).

Pinout

- Pin count: 8 pins (8-pin package).
- Function: MIC809-5SYC3-TR is an 8-pin watchdog timer/reset IC. It monitors a heartbeat on its watchdog input (WDI) and, if the interval times out, asserts its watchdog output (WDO) to reset the system. It includes VDD and GND and typically uses an external RC network to set the timeout. The “-5” indicates a 5V variant; “TR” denotes tape-and-reel packaging.

Manufacturer

Manufacturer: Micrel, Inc. (now part of Microchip Technology).
What kind of company: Micrel was a fabless American semiconductor company that designs and markets analog and mixed-signal integrated circuits (now part of Microchip Technology).

Application

MIC809-5SYC3-TR is a voltage detector/reset generator. Typical applications:
- Microcontroller and digital-logic reset supervision
- Power-on/brown-out reset protection
- Battery-powered/portable devices
- Embedded systems requiring reliable restart on supply fluctuation
- System sequencing and safe startup for SoCs
These use cases protect data integrity and ensure proper device startup during supply variations.
