Descripción general

Description

MAX809JEUR+T is a Maxim (now Analog Devices) microprocessor‑reset/voltage‑supervisor IC. It monitors Vcc and asserts an active reset to a microcontroller when the supply is too low or during power‑up/power‑down to ensure reliable MCU startup.
Key points:
- Fixed-threshold reset: available in several variants (thresholds such as around 2.63 V, 2.93 V, 4.63 V, etc. – choose variant as needed).
- Reset output: TTL/CMOS‑compatible, typically active-low; may include a small internal delay to guarantee a clean reset pulse.
- Simple hookup: Vcc and GND, with the reset pin connected to the MCU; add decoupling near the device.
- Optional features: manual reset input (MR) on some parts; extremely low quiescent current.
- Packaging suffix: JEUR indicates RoHS lead-free variant; “+T” indicates Tape & Reel packaging.
Use it to protect microcontrollers during power-up/brown-out without external timers. For exact thresholds, timing, and pinout, consult the MAX809 datasheet for the specific variant you’ve chosen.

Features

Here are the key features of MAX809JEUR+T (MAX809 family, industrial/Europe temp, Tape & Reel):
- Microprocessor reset supervisor with power-on reset (POR) for clean MCU startup
- Manual reset input (MR) to force a reset
- Reset output (active-low) to MCU
- Wide supply voltage range (typical operation around 2.7V–5.5V; exact range per variant)
- Very low quiescent current (typical microamps in reset)
- Industrial/extended temperature variant (JEUR) for -40°C to +85°C (or higher, depending on exact spec)
- RoHS-compliant; +T denotes Tape & Reel packaging
- Available in 8-pin package (and similar) for easy PCB integration
Note: Exact voltage thresholds, timing, and pinout can vary by specific MAX809 variant; consult the datasheet for precise electrical characteristics.

Package

8-pin Small-Outline Integrated Circuit (SOIC-8). The +T suffix denotes Tape-and-Reel packaging.

Pinout

Pin count: 3 pins.
Function: MAX809JEUR+T is a microprocessor reset supervisor (voltage detector). It monitors Vcc and generates a reset signal for a MCU when the supply falls below its threshold; the reset output is active-low. The three pins are Vcc, GND, and RESET (out). The +T denotes Tape & Reel packaging.

Manufacturer

- Manufacturer: Maxim Integrated Products (now part of Analog Devices).
- What kind of company: A semiconductor company that designs and manufactures analog and mixed-signal integrated circuits, including voltage detectors and supervisory ICs.

Application

Applications of MAX809JEUR+T:
- Microcontroller/microprocessor reset supervision and generation
- Power-on reset and brown-out protection for 3–5V digital circuits
- Reset control for FPGAs, DSPs, and ASICs
- Battery-powered/portable electronics and IoT devices
- Automotive and industrial electronics requiring reliable POR
- Safe power-down sequencing and basic system health monitoring
(Note: MAX809 is a voltage supervisor; it guarantees deterministic reset during power anomalies.)

Equivalent

Equivalent parts (voltage supervisor/microprocessor reset ICs) to MAX809JEUR+T include:
- TI TLV803 series (TLV803/TLV803B)
- Microchip MCP1316/MCP1317 series
- Analog Devices ADM803/ADM803A
- ON Semiconductor NCP301/NCP302/NCP300 series
Note: choose with matching supply range, reset threshold, and timing; verify package and tape-and-reel availability.
