STMicroelectronics STM6600 and STM6601 Smart Pushbutton Controllers

STMicroelectronics announced the STM6600 and STM6601 smart pushbutton on/off controller chips for battery-powered embedded systems like e-readers, tablets, media players, smartphones, and digital cameras. The STM6600 and STM6601 on/off controller chips will enable next-generation mobile products to offer easy-to-use ‘power-up’, ‘power-down’ and ‘unfreeze/reset’ functions that will prevent damage to the end-user product. The STM6600 and STM6601 are in volume production now. Several configurations are available, allowing designers to optimize protection for their designs, priced from $0.65 in quantities of 10,000.
