Pushbutton Controller Chips suit battery-powered products.

Model STM6600 and STM6601 smart pushbutton on/off controller chips block device power-up if battery is excessively discharged. Chips can also prevent power-up if fault is detected in power supply. Connecting directly to power button, ICs use smart-reset, which requires 2 pushbuttons to be held down for minimum period before reset occurs, eliminating need to hide reset button. Units have active...
