概述

Description

MAX708ESA is an 8‑pin microcontroller reset/voltage‑supervisor IC from Maxim Integrated (MAX708 family). It monitors the system supply and timeouts to generate a reset to a microcontroller, ensuring startup stability and protection against brownouts. Typical features include automatic power‑on reset, a watchdog timer that can reset the MCU if software hangs, a manual reset input, and a push‑pull (or open‑drain) reset output compatible with CMOS/TTL inputs. The device operates over a broad supply range with low current consumption, suitable for battery-powered and embedded applications. The “ESA” suffix indicates the package/temperature rating (eight‑pin package, RoHS‑compliant with extended/industrial temperature range). For exact electrical specs (thresholds, reset polarity, watchdog timeout, timing, and pinout), consult the current Maxim datasheet for MAX708ESA.

Features

MAX708ESA is an 8-pin microprocessor supervisory circuit with watchdog. Key features:
- Single-supply operation (typically 4.5V–5.5V)
- Power-on reset (POR) to guarantee MCU reset on power-up
- Watchdog timer with external control via WDI; timeout interval set by external components
- Manual reset input (active-low)
- Active-low, push-pull reset output
- Low quiescent current
- Wide temperature range (e.g., -40°C to +85°C)
- Small 8-pin package (SOP/DIP variant) suitable for low-footprint designs
Typical use: provide MCU reset supervision and watchdog protection to recover from stuck software or brownouts.

Package

MAX708ESA is in an 8-pin small-outline package: SOIC-8 (SOP-8).

Pinout

- Pin count: 8 pins.
- Function: MAX708ESA is a microprocessor supervisory device with a watchdog timer. It monitors Vcc and provides a reset to the MCU on power-up/power-down or if the watchdog times out; includes a watchdog input and a reset output (used to supervise microcontroller operation).

Manufacturer

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

Application

Applications of MAX708ESA include:
- Microcontroller/processor reset generation with brown-out protection
- Watchdog timer for system fault detection and recovery
- Memory reset and overall system supervision in embedded controllers
- Battery-powered/portable devices requiring reliable reset signals
- Automotive and industrial embedded controllers and similar leverage areas
