Overview

Description

MAX809SN293D2T1G is a MAX809 family microprocessor supervisory circuit with a fixed 2.93 V reset threshold. It monitors the supply rail and asserts an active-low reset output to a microcontroller whenever Vcc falls below 2.93 V or during power-up, providing brown-out protection and reliable MCU startup. The device draws very low quiescent current and requires no external components for basic operation. SN293 denotes the 2.93 V version (suitable for ~3 V logic); D2/T1G identify the package (small, RoHS-compliant SOT-23-3) and packaging/temperature options. Typical applications include reset for microcontrollers in battery-powered or 3 V systems and general power-on/brown-out reset protection. How to use: connect V+ to the supply, GND to ground, and route RESET# to the MCU’s reset line; RESET# will pull low on undervoltage and release after the supply stabilizes and the internal delay expires. For exact electrical specs and timing, consult the MAX809 datasheet.

Package

SOT-23-3 (SC-70-3) 3-pin package, RoHS/lead-free.

Pinout

Pin count: 3 pins (V+, GND, RESET output).
Function: MAX809SN293D2T1G is a microprocessor reset supervisor with a fixed 2.93 V threshold. It continuously monitors Vcc and asserts a reset signal to the microcontroller when the supply falls below the threshold or during power-up until the voltage is stable. The reset output is active-low.

Manufacturer

Manufacturer: Maxim Integrated, now part of Analog Devices, Inc.
What kind of company: A global semiconductor company that designs and manufactures analog and mixed-signal integrated circuits (an integrated device manufacturer, IDM).

Application

MAX809SN293D2T1G is a 2.93V reset supervisor. Typical application areas:
- Microcontroller/microprocessor reset supervision in 3–5V systems
- Power-on reset and brown-out protection for embedded controllers, FPGAs, DSPs
- Reset generation for digital ICs during supply fluctuations
- Voltage supervision in battery-powered/portable devices
- System reset supervision in consumer electronics and control/communication boards

Equivalent

Equivalent parts (2.93 V fixed reset threshold, similar behavior) include:
- TI TPS3800/TPS3810 family
- Microchip MCP130/MCP131 family
- ON Semiconductor NCP301/NCP131 family
- Analog Devices ADM809/ADM809A
Note: exact package (D2, T1G), reset delay, and voltage window vary by part. Use a distributor cross-reference (e.g., DigiKey/Mouser) to map package and timing precisely.
