2.8V-threshold supervisor for processor power-rail monitoring
The MAX6340UK28: It belongs to the Simple Reset/Power-On Reset family, designed for processor, FPGA, and ASIC power-on reset sequencing. The reset timeout period is adjustable or selectable, giving the designer control over the delay after the supply returns above threshold. Operating temperature spans -40°C to +125°C, covering the industrial and automotive ambient range. This makes it suitable for engine-bay electronics, industrial controllers, and outdoor telecom gear where the board sees wide thermal cycling.
SOT-23-5 footprint and board integration
Housed in the SOT-23-5 package (SC-74A, SOT-753 equivalent), the MAX6340UK28 occupies minimal PCB area. The five-pin layout routes VCC, GND, RESET, and the timeout-adjust pin — a single decoupling cap near the supply pin is the only external component needed for basic operation.
