概要

Description

MAX706CSA is a microprocessor supervisory/reset IC from Maxim (now part of Analog Devices). It monitors the supply voltage and generates a clean reset signal to a microcontroller when Vcc is out of range or during power-up/power-down, helping ensure reliable MCU startup and operation. The CSA suffix denotes a specific package/temperature variant for the device (for example, a particular 8-pin package and operating range). Features typically include a reset output (and often a power-on reset delay and a manual reset input), all with very low quiescent current suitable for battery-powered designs. Application areas include MCU resets in embedded and portable systems, power-fail monitoring, and hardware watchdog-style reset protection. For exact thresholds, delay timing, pinout, and package/temperature details, consult the MAX706CSA datasheet.

Features

Here are the typical features of the MAX706CSA (microprocessor supervisor with watchdog):
- Power-On Reset (POR) with brown-out detection
- Built-in watchdog timer that requires periodic refresh to avoid reset
- Manual reset input
- Reset output (active-low) to drive MCU reset line
- Low quiescent current; suitable for battery-powered applications
- Wide supply range (variant-dependent; CSA versions commonly in 4.5V–5.5V category; check datasheet for exact range)
- 8-pin package (CSA), industrial temperature range
- Robust operation with timing stability and reset glitch rejection
- RoHS compliant and ESD-protected inputs/outputs
Note: Exact voltage thresholds, timing options, and pinout can vary by variant and package; consult the MAX706CSA datasheet for precise specifications.

Package

MAX706CSA comes in a 6‑pin SC‑70 (SOT‑23‑6) package.

Pinout

- Pin count: 8 pins (8‑pin package, e.g., SOIC).
- Function: Microprocessor supervisory/reset IC with voltage monitoring, power-on reset, and a watchdog. It asserts an active-low reset output when Vcc is low or the watchdog is not toggled, and typically provides inputs for manual reset and watchdog control.

Manufacturer

Manufacturer: Maxim Integrated Products (now part of Analog Devices, Inc., ADI).
What kind of company: A global semiconductor company that designs and manufactures analog and mixed-signal integrated circuits, including power-management and supervisory devices.

Application

Typical applications for MAX706CSA:
- Microprocessor/microcontroller reset and watchdog in battery-powered/portable devices
- Power-on/brown-out reset for embedded systems
- Automotive, industrial control, and consumer electronics needing reliable reset signaling
- Data acquisition and telecom equipment requiring deterministic reset control

Equivalent

MAX706CSA is a low‑power microprocessor supervisor (voltage monitor with reset). There isn’t a single direct cross‑reference. Functionally equivalent devices include:
- Maxim: MAX809/MAX810 family
- TI: TLV803 / TPS3800
- Microchip: MCP1316 / MCP1317
- On Semiconductor: NCP301 / NCP302
When selecting, match reset threshold (Vth), supply range, and reset output type (push-pull vs open-drain).
