概述

Description

NCP302HSN45T1G is an On Semiconductor automotive-grade high-side switch IC. It integrates a switch MOSFET with protection features to drive a load directly from a supply up to 45 V.
Key points:
- High-side load switch with enable control
- Protection: reverse polarity, overcurrent, and thermal shutdown
- Suitable for automotive/industrial and battery-powered applications
- Small package (HSN family) for compact designs
Typical usage:
- Vin to supply, Vout to the load, GND to system ground
- EN pin to enable/disable the switch
- Use the On Semiconductor datasheet for exact electrical specs, pinout, and application notes.
For precise characteristics and pin configuration, refer to the NCP302HSN45T1G datasheet on On Semiconductor’s website.

Features

NCP302HSN45T1G key features:
- Fixed 4.5 V voltage detector for MCU/system reset
- Power-on reset ensures reset is released only after VCC stabilizes
- Manual reset input to force a reset externally
- Reset output is active-low and drives MCU reset
- Low quiescent current for low-power applications
- Wide operating temperature range (-40°C to 125°C)
- Small, RoHS-compliant package (HSN/T1G family footprint)
Typical use: storyboard-style voltage supervision and MCU reset in 4.5 V systems.

Package

It uses the HSN package – a small 3‑lead SC‑70/SOT‑353 style package (3 pins) from ON Semiconductor.

Pinout

- Pin count: 6 pins
- Function: Fixed-output low-dropout regulator (LDO) with 4.5 V output, in a 6‑pin SOT‑23/SC‑74A package (NCP302HSN45T1G).

Manufacturer

Manufacturer: ON Semiconductor.
What kind of company: An American multinational semiconductor company that designs, manufactures, and sells a broad range of ICs and discrete components (power management, sensors, logic, etc.).

Application

Typical application areas for NCP302HSN45T1G:
- Portable and battery-powered devices (core/rails regulation)
- Consumer electronics and smart devices
- Telecom and networking equipment
- Industrial and automotive power-management applications
