The is a low cost, power-on reset and watchdog controller in 16 pin WSOIC package. The device monitors +5V supply in microprocessor µP and digital systems. It supplies a RESET complementary pulse of at least 140ms duration on power-up, power-down and during low voltage brownout conditions. Circuit reliability is increased at reduced cost by eliminating all external components and adjustments. It also provides a watchdog input to monitor microprocessor activity. The RESET complementary output goes low if the watchdog input WDI is not toggled within 1 second. The watchdog feature can be disabled by leaving WDI open. Typical applications include intelligent instruments, controllers, computers and critical & µP power monitoring.
