MAX6503UKN035+T

MAX6503UKN035+T is a Maxim Integrated microprocessor supervisory device. It combines a voltage monitor with a reset output and an optional watchdog timer to ensure a microcontroller starts correctly on power-up and remains responsive during operation. When Vcc is above the reset threshold and the watchdog (if used) is serviced in time, the device releases the MCU reset; if Vcc falls or the software fails to “kick” the watchdog, reset is asserted again. The +T suffix indicates Tape & Reel packaging; UKN is the supplier’s package/ordering code (including lead-free options). Typical uses include lightweight, low-power protection for microcontrollers or DSPs in embedded or battery-powered systems, with a small pin count and easy integration. For exact voltage thresholds, timing, pins, and package details, refer to the MAX6503 datasheet and packaging specification.

- Pin count: 8 pins (package: 8‑pin SOIC/µSOIC).
- Function: Fixed-threshold voltage supervisor/reset IC for microcontrollers. Monitors VCC and asserts the reset output when VCC drops below 3.5 V (threshold 3.5V); +T indicates extended temperature range.

- 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.

8-pin SOIC (surface-mount) package (SOIC-8); +T indicates tape-and-reel version.
