STM1001MWX6F ST Supervisors

The STM1001MWX6F is a low-power microprocessor supervisor (reset circuit) from STMicroelectronics in SOT-23-3 package, monitoring 4.38V supply threshold with active-low open-drain reset output . For selection, verify supply voltage from 1V to 5.5V, reset threshold of 4.38V with ±2% accuracy (suitable for 5V systems), 140ms minimum reset timeout, ultra-low supply current of 6µA typical, and operating temperature from -40°C to +85°C . Features include open-drain reset output requiring external pull-up resistor, guaranteed reset valid down to 1V VCC for reliable power-on reset, excellent immunity to negative VCC transients, and no external components required. Ideal for 5V microprocessor and microcontroller systems, industrial controllers, portable equipment, battery-powered devices, automotive electronics, and embedded systems requiring power-on reset and brown-out protection with 4.38V threshold monitoring for 5V supply rails .
