Pin Function
Active-High Push-Pull Reset Output. This output changes from low-to-high when VIN drops below the
selected reset threshold or both manual reset pins are pulled low for the setup delay period. RSTP
remains high for the reset timeout delay after VIN exceeds the reset threshold plus hysteresis voltage
or the setup delay period has elapsed.
Supply Ground.
Active-Low Manual Reset Input. The MIC2786 has an internal 65k ? pull-up resistor to VIN, while the
MIC2787 requires an external pull-up resistor to VIN if used with a push button. Pull this pin low to
assert and force a reset. Pulling both manual reset inputs low for the setup delay time causes one
reset output pulse for the reset timeout delay period. Connect to VIN if unused, do not leave floating.
Active-Low Open-Drain Reset Output. This output changes from high-to-low when VIN drops below
the selected reset threshold or both manual reset pins are pulled low for the setup delay period. /RST
remains low for the reset timeout delay after VIN exceeds the reset threshold or the setup delay has
elapsed and it requires an external pull-up resistor.
Programmable Delay Input with Tri-State Connection. When left open, setup delay is 2s, when
connected to GND, setup delay is 4s and when connected to VIN, setup delay is 6s.
No Connect. Leave pin floating.
Active Low Manual Reset Input. The MIC2786 has an internal 65k ? pull-up resistor to VIN, while the
MIC2787 requires an external pull-up resistor to VIN if used with a push button. Pull this pin low to
assert and force a reset. Pulling both manual reset inputs low for the setup delay time causes one
reset output pulse for the reset timeout delay period. If unused, connect to VIN; do not leave floating.
Supply Voltage Pin. It is the input to the Supply Voltage monitor. When the supply voltage falls below
the reset threshold voltage, reset outputs (/RST and RSTP) are triggered immediately. When the
supply voltage rises above the reset threshold plus hysteresis voltage, the reset outputs remain
asserted for the duration of the reset timeout delay. A minimum 0.1 μ F decoupling ceramic capacitor
must be connected between VIN and GND close to the pins.
Exposed Pad. Connect to GND.
