概述

Description

MAX708TESA is a Maxim Integrated microprocessor supervisory device (part of the MAX708 family) used to monitor supply voltage and protect microcontrollers and digital logic. It generates a reset signal when the supply voltage falls outside safe limits and, on some variants, may include a watchdog timer and a manual reset feature to ensure system reliability. The “TESA” suffix denotes a specific package/temperature grade variant. Typical use cases include brown-out protection, safe startup/shutdown sequencing, and watchdog-assisted resets in embedded systems and battery-powered applications. For exact voltage thresholds, timing, power consumption, and package details, refer to the MAX708TESA datasheet.

Features

Here are the key features of the MAX708TESA (microprocessor supervisory with watchdog):
- Wide supply range: typically 2.7V to 5.5V (suitable for 5V and 3.3V systems)
- Power-on Reset (POR) with guaranteed reset during power-up
- Manual reset input (MR) for external reset
- Independent watchdog timer with a feed/input (WDI) to prevent reset
- Reset output (active-low RESET#) that asserts during POR, undervoltage, or watchdog timeout
- Undervoltage/voltage-detection with noise filtering for robust operation
- Low quiescent current (suitable for battery-powered applications)
- Extended temperature version: -40°C to +85°C (ESA grade)
- 8-pin package (TSSOP/SOIC style, Pb-free variant)
Applications: microcontroller/microprocessor reset supervision, embedded systems requiring watchdog monitoring and reliable startup/reset behavior.

Package

MAX708TESA comes in an 8-pin Small Outline Integrated Circuit package (SOIC/SOP-8).

Pinout

Pin count: 8 pins (DIP-8/SOIC-8). Function: microprocessor supervisory circuit with voltage detector and watchdog timer; provides a reset output to a microcontroller on power-up/power-down or when the watchdog expires.

Manufacturer

Manufacturer: Maxim Integrated (now part of Analog Devices).
What kind of company: A semiconductor company that designs and sells analog and mixed-signal integrated circuits; it is a fabless company (uses external foundries for manufacturing).

Application

Applications of MAX708TESA:
- MCU/MPU reset generation and brown-out protection
- Power-on reset for single-supply systems
- Watchdog supervision in embedded systems
- Battery-powered devices with low quiescent current
- Automotive/industrial control electronics needing reliable reset
- Multi-voltage systems requiring robust reset supervision

Equivalent

MAX708TESA is a MAXIM voltage supervisor/reset IC (MAX700 family). Suitable equivalents from other vendors include:
- Analog Devices ADM706/ADM707/ADM708 voltage supervisors
- TI TPS3800/TPS3810/TPS3836 voltage detectors
- Microchip MCP130/MCP131/MCP132 voltage supervisors
Choose by: Vcc range, reset threshold, reset delay, and active-low/high reset. Also confirm whether a watchdog function is required, as MAX708 variants differ in that regard.
