Description
The R8358 Series are CMOS-based system power ICs with a voltage detector (VD) and watchdog timer (WDT) integrated in a single chip. R8358 monitors the power system of devices equipped with microprocessors and prevents system runaway with a reset signal when a malfunction occurs. R8358 is equipped with the function that inhibits clock monitoring of the WDT (INH). Since R8358 has a SENSE pin for monitoring voltage separately from the power pin, its reset signal does not become unstable under the condition that the power supply is sufficient to operate the IC, and the "L" can be maintained.
