概要

Description

NCP803SN293D3T1G is an ON Semiconductor voltage supervisor/reset IC in the NCP803 family. It monitors VDD and asserts a reset output when the supply falls below a fixed threshold of about 2.93 V (as indicated by the 293 in the suffix). The device provides a clean reset signal for microcontrollers during power-up and power-down, helping prevent malfunctions from brown-outs. It’s a small, RoHS-compliant device (D3/T1G package) with features typical of MCU supervisors, such as low quiescent current and an intrinsic reset delay/glitch filtering. The reset output is designed to be MCU-friendly (often active-low, open-drain or push-pull, depending on variant). No external components are required for basic operation, though exact pinout, reset polarity, delay times, and operating ranges are specified in the datasheet. Use it for reliable MCU/digital IC reset supervision in power-sensitive designs. For precise electrical characteristics and packaging details, consult the NCP803SN293D3T1G datasheet.

Package

SOT-23-5 (SC-70-5) small surface-mount package.

Pinout

Pin count: 3 pins (SOT-23-3 package).
Function: A voltage supervisor (reset IC) with a fixed 2.93 V threshold. It monitors Vcc and provides an active-low reset output (RESET#) that is asserted on brown-out/power-down and released when Vcc rises above the threshold. No external reset input.

Manufacturer

- Manufacturer: ON Semiconductor (Onsemi).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, power, and mixed-signal ICs and discrete components for automotive, industrial, and consumer markets.

Application

Application areas: Microcontroller and digital IC reset supervision; power-on/brown-out reset in 2.7–3.6 V systems; battery-powered devices; portable electronics; embedded systems; IoT sensors; data loggers; USB peripherals.

Equivalent

Equivalent parts (2.93 V reset threshold) from other vendors:
- TI TLV803 family (2.93 V variant)
- Microchip MCP1316/MCP1317 series
- Maxim MAX809/MAX810 (2.93 V option)
- Analog Devices ADM803/ADM809
Note: exact drop-in suitability depends on package, timing/hysteresis, and output type. Verify current/specs against NCP803SN293D3T1G.
