Übersicht

Description

ADM690AN is Analog Devices’ microprocessor supervisory circuit (voltage detector with watchdog). It monitors the supply (VCC) and provides a reset signal to a microcontroller or processor. Key features typically include:
- Power-on reset: ensures a known reset state on startup.
- Undervoltage detection: asserts reset if VCC falls below the threshold.
- Watchdog timer: can reset the processor if software fails to “kick” the watchdog.
- Manual reset input: allows external forcing of a reset.
- Reset output: TTL/CMOS-compatible, usually active-low (open-drain or push-pull).
- Package: commonly 8-pin (AN suffix denotes a specific package/grade).
Use: to improve system reliability in embedded designs by guaranteeing proper startup and recovering from brownouts or software hangs.

Features

ADM690AN is an 8-pin microprocessor supervisor with a watchdog timer. Key features:
- Power-on reset (POR) to ensure known state at Vcc start-up
- Watchdog timer with external WDI input (must be toggled to prevent reset)
- Manual reset input ( MR ) for external reset control
- Reset output (active-low) with open-drain or push-pull option (layout dependent)
- Wide operating voltage range (typical 2.7V–5.5V)
- Low quiescent current
- Suitable for CMOS/TTL microprocessor interfaces
- Compact 8-pin package (variant N)
Note: For exact voltage thresholds, timing, and package specifics, please refer to the official ADM690AN datasheet.

Package

ADM690AN is an 8-pin device in a small-outline package, typically SOIC-8 (8-lead), RoHS-compliant.

Pinout

8 pins (8‑pin package, e.g., DIP-8/SO-8).
Function: ADM690AN is a microprocessor supervisory circuit with voltage monitoring and a watchdog. It monitors the supply voltage and provides a reset signal to the CPU. It also supports a watchdog input and a manual reset, and outputs an active-low reset (RESET#) when the voltage is out of range or the watchdog expires.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI).
- Company type: A multinational semiconductor company specializing in analog, mixed-signal, and digital signal processing (DSP) integrated circuits for industrial, automotive, communications, and consumer markets.

Application

ADM690AN is a voltage supervisor/reset IC. It monitors Vcc and generates a reset on power‑up/power‑down or when the rail drops below a threshold.
Applications:
- MCU/FPGA/SoC reset generation
- Brown‑out and power‑on reset protection
- Safe start-up sequencing in single/multi‑voltage systems
- Embedded digital electronics in automotive, industrial, and battery‑powered equipment requiring reliable reset signaling

Equivalent

Equivalents to ADM690AN (voltage supervisor/reset IC) include:
- Maxim: MAX690, MAX691, MAX692
- Texas Instruments: TLV803 (and TLV803B), TPS3808/TPS3809
- Microchip: MCP131 / MCP132 / MCP138 series
