概述

Description

NCP433FCT2G is ON Semiconductor’s fixed-threshold voltage supervisor (reset IC). It monitors Vcc and generates a deterministic reset signal to a microcontroller or digital logic when the supply is below its threshold or during power-up/power-down.
Key points:
- Fixed-threshold reset supervisor with predefined voltage trip point (variant-dependent) and built-in hysteresis.
- Provides a defined reset output to ensure reliable MCU startup; timing/pulse width specified in the datasheet.
- Very low quiescent current, suitable for battery-powered and energy-conscious designs.
- Package code FCT2G denotes a compact package variant; exact pinout and package details are in the datasheet.
Common uses:
- Microcontroller/FPGA/basically any digital logic reset at brown-out or power-on.
- Power-on reset and brown-out protection in embedded systems.
Note:
Exact threshold, reset polarity, timing, and package/pinout vary by variant. Check the datasheet for the precise numbers and the intended package.

Features

NCP433FCT2G is a microprocessor supervisor (voltage detector) with reset generation. Key features:
- Fixed-voltage threshold variants (POR/RESET when Vcc falls below threshold)
- Wide operating supply range (typical 1.65–5.5 V)
- Reset output: active-low, push-pull
- Manual reset input for external forcing of reset
- Fast, glitch-free power-on reset with defined minimum pulse width
- Very low quiescent current (microamp range)
- Robust against brown-out and fast transients
- Temperature range: -40°C to +125°C
- Small, RoHS-compliant package (FCT2G family) suitable for compact designs
Note: Specific threshold voltages and package options depend on the exact variant; refer to the datasheet for the precise values.

Package

SOT-23 (SC-70-3) surface-mount package.

Pinout

- Pin count: 5 pins (SOT-23-5/SC-70-5 package).
- Function: Microprocessor reset supervisor (voltage detector). It monitors VCC and generates an reset signal for a microcontroller when supply voltage falls below its threshold (reset output typically active low), providing brown-out protection.

Manufacturer

Manufacturer: ON Semiconductor (ON Semiconductor Corporation).
