General Description

TO-92 1 RST 2 VCC 3 GND Active High Reset Output Power Supply Ground SOT-23 1 RST 2 VCC 3 GND Active High Reset Output Power Supply Ground DESCRIPTION The DS1812 EconoReset uses a precision temperature reference and comparator circuit to monitor the status of the power supply (VCC).

When an out-of-tolerance condition is detected, an internal power-fail signal is generated which forces reset to the active state.

When VCC returns to an in-tolerance condition, the reset signal is kept in the active state for approximately 150 ms to allow the power supply and processor to stabilize.
