ILC1832 - uP SUPERVISORY CIRCUIT

Datasheet Summary

Features

  • The ILC1832 is a multifunction circuit which monitors microprocessor activity, external reset and power supplies in microprocessor based systems. Ths circuit functions include a watchdog timer, power supply monitor, microprocessor reset, and manual pushbutton reset input. The power supply line is monitored with a comparator and an internal voltage reference. RST is forced low when an out-of-tolerance condition exists and remains asserted for at least 250ms after VCC rises above the threshold vo.

Impala Linear Corporation ILC1832 Preliminary µP Supervisory Circuit General Description Features The ILC1832 is a multifunction circuit which monitors microprocessor activity, external reset and power supplies in microprocessor based systems. Ths circuit functions include a watchdog timer, power supply monitor, microprocessor reset, and manual pushbutton reset input. The power supply line is monitored with a comparator and an internal voltage reference. RST is forced low when an out-of-tolerance condition exists and remains asserted for at least 250ms after VCC rises above the threshold voltage (2.55V or 2.88V). The RST pin will remain logic low with VCC as low as 1.4V.
