Pin-Selectable, Hex Power-Supply

Supervisory Circuit

the IN inputs only at power-up. Use the voltage-divider

circuit of Figure 1 and Equation 1 to set the threshold

for the user-adjustable inputs as described in the

Voltage-Detector Inputs (IN_) section.

Manual Reset (MR)

Many microprocessor-based (µP) products require

manual reset capability to allow an operator or external

logic circuitry to initiate a reset. The manual reset input

(MR) can be connected directly to a switch without an

external pullup resistor or debouncing network. MR is

internally pulled up to DBP. Leave unconnected if not

used. MR is internally pulled up to DBP through a 10µA

current source. MR is designed to reject fast, falling

transients (typically 100ns pulses) and must be held low

for a minimum of 1µs to assert RESET. After MR transi-

tions from low to high, RESET remains asserted for the

duration of its timeout period.
