STMicroelectronics introduce smart switch button controller chip
STMicroelectronics has introduced two new intelligent switch button controller chip, can enhance the mobile user experience. New products suitable for almost all battery-powered portable devices, including the ebook reader, portable computers, media players, smart phones and digital cameras. Both new products will enable the next generation of mobile products with more easy to use "boot", "shutdown" and "unlock / reset" function, to avoid damage to the end-user products. In addition, these single-chip solution for the overall market leader in mobile and portable electronics manufacturers to simplify the design work in product design using a chip to replace dozens of discrete devices.
STM6600 and STM6601 new smart switch button controller chip for battery-powered products offer different protection. These include reduced due to lack of battery power can not be completed when the system boot damage. To prevent such damage occurs, the chip in the battery power is low will prevent the system boot. Found an error in the power, the chip will stop the system boot. The new chip directly connected to the power button, the system can be connected to another SmartResetTM enter any of the other keys, the built-in protection circuit prevents external interference (such as electrostatic discharge) caused unnecessary boot or system reset.
STMicroelectronics as the latest power path management IC, STM660x series smart chip reset function to help users operate the normal occurrence of system failure or when the machine back to normal. Smart reset input by an external capacitor control, users need to hold down two buttons can reset a few seconds after the entry into force. To prevent accidents or misuse, today's design needs to hide in case the reset button hole, and now ST's dual-action reset design is no need to punch holes in the chassis, thus reducing the project cost equipment manufacturers, such as the need to also chassis can be designed as closed.
STM660x integrated protection products can replace as many as 30 or 40 discrete devices, or sold separately with regulators, clock, and determine the condition of the battery voltage detector complex programming logic device (CPLD). Equipment manufacturers can use a built-in dedicated housekeeping functions ? micro-controllers, Dan this solution programs also require an external crystal and voltage detection device, and also programming.
STM660x a 2x3mm package, the PC board footprint is less than 50% of other solutions for mobile products to save valuable space. It 6?A low operating power and current consumption is less than 1?A of zero-power shutdown mode, are very important for the mobile product designers to feature.
STM6600 and STM6601 now in volume production. The new products offer a variety of configurations, designers can achieve higher product design protection.
