STM66xx Smart Push-Button On / Off Controller

STMicroelectronics STM6600/STM6601 Smart Push-Button On / Off Controllers with Smart Reset™ and power-on lockout protects against the hazards faced by battery-operated devices. These types of devices include smartphones, digital cameras, and media players. The STM6600/STM6601 controllers enable and disable power for the application depending on push-button states, signals from the processor, and battery voltage. If the battery is excessively discharged or a fault is detected in the power supply, the IC blocks power-up. These devices also implement smart-reset capabilities to enable users to safely recover gadgets that have frozen or crashed during normal operation. The STM6600/STM6601 controllers connect directly to the power and reset buttons and have circuitry to prevent external interference such as electrostatic discharges. These devices feature a very low current consumption of 6µA in normal operation and only 1µA during standby, resulting in virtually no battery drain when the application is turned off.
