概述

Description

The MAX810LTRG is a Maxim microprocessor supervisory circuit. It monitors Vcc and provides a clean reset for a microcontroller or digital IC during power-up, power-down, or when the supply dips outside a valid range. It includes an internal power-on reset delay to guarantee a valid reset interval after Vcc becomes stable. The RESET output is typically active-low, and there is a manual reset input to force a reset externally. The device is available in multiple threshold versions (e.g., around 2.93 V, 4.63 V) for 2.7–5.5 V systems. The LTRG suffix indicates lead-free RoHS-compliant packaging in Tape-and-Reel. Common uses include MCU reset supervision in embedded systems, consumer electronics, and battery-powered devices. In operation: once Vcc rises above the chosen threshold and the POR delay expires, RESET releases (inactive). If Vcc falls below the threshold or a manual reset is asserted, RESET goes active-low to reset the MCU.

Features

Concise features of MAX810LTRG:
- Single-supply voltage supervisor with automatic reset on power-up/power-down
- Manual reset input to force an immediate reset
- Reset output is active-low (TTL/CMOS compatible)
- Internal POR (power-on reset) timer ensures a defined reset period
- Very low quiescent current in normal operation
- Wide operating voltage range suitable for 3V and 5V systems (typical 2.7V–5.5V, check datasheet)
- 8-pin package; LTRG suffix indicates Pb-free, Tape & Reel packaging
- Simple, robust reset for microprocessors/microcontrollers and digital ICs

Package

MAX810LTRG uses an 8-pin SOIC (surface-mount) package, RoHS/lead-free, and is supplied in Tape & Reel.

Pinout

- Pin count: 8 pins (8-pin package)
- Function: Microprocessor reset supervisor. Monitors Vcc and asserts a reset output when supply falls below a threshold (with power-on reset) and provides a manual reset input; reset output is active-low.

Manufacturer

- Manufacturer: Maxim Integrated Products, Inc. (now a subsidiary of Analog Devices).
- What kind of company: An American semiconductor company that designs and sells analog and mixed-signal integrated circuits (historically fabless, outsourcing fabrication).

Application

Application areas of MAX810LTRG:
- Reset and brown-out protection for microcontrollers/microprocessors
- Power-on reset for CPUs, FPGAs, DSPs, and memories
- Battery-powered/portable devices needing reliable reset during supply fluctuations
- Embedded systems and consumer electronics requiring deterministic reset timing and safe start-up
- Power-fail detection in small appliances, data loggers, and other digital systems

Equivalent

Equivalent parts (voltage supervisor/reset ICs) from other vendors include:
- TI TLV803 / TLV803A
- Microchip MCP1316 / MCP1317
- Analog Devices ADM803 / ADM809
- ON Semiconductor CAT810 / CAT811
These offer similar reset-output supervision for microcontrollers in compatible voltage ranges.
