The integrated reset and watchdog function, as well as several protection circuits, combined with a wide operating temperature range offered by the TLE4678-2EL make it suitable for supplying microprocessor systems in automotive environments.The watchdog circuitry will be disabled in case the output current drops below a programmable threshold, enabling a microcontroller to switch in stand-by mode. Modifying the reset threshold is possible by an optional resistor divider. The TLE4678-2EL is available in PG-SSOP-14 exposed pad package. Alternatively, the TLE4278-2 is also available in PG-TSON-10 exposed pad package as TLE4678-2LD, featuring thermally enhanced package performance.
