RESETN

Active-Low Reset Output (AS1910, AS1912, AS1913, AS1915). The RESETN signal

reset threshold (see Table 4 on page 4), or MRN is pulled low, or the watchdog triggers a

reset. This output signal remains low for the reset timeout period after all supervised voltages

exceed their reset threshold, or MRN goes low to high, or the watchdog triggers a reset.

RESET

Active-High Reset Output (AS1911, AS1914). The RESET signal toggles from low to high

Table 4 on page 4), or MRN is pulled low, or the watchdog triggers a reset. This output signal

exceed their reset threshold, or MRN goes low to high, or the watchdog triggers a reset.

3MRN

Active-Low Manual Reset Input. Pulling this pin low asserts a reset. This pin is connected

to the internal 50k

Note: If the manual reset feature is not used, this pin should be unconnected or connected

4WDI

Watchdog Input. If WDI remains high or low for longer than the watchdog timeout period

reset is a asserted or when WDI senses a rising or falling edge.

Note: To disable the watchdog feature, this pin must be unconnected or connected to a tri-

state buffer output.

RESETIN

User-Adjustable Supervised Voltage Input (AS1910/AS1911/AS1912). This high-

impedance pin serves as the input to the internal reset comparator. Connect this pin to an

external resistor-divider network to set the reset threshold voltage (down to 0.63V).

Primary Supervised Voltage Input (AS1913/AS1914/AS1915). This pin serves as the

secondary supervised voltage input.

Primary Supervised Voltage Input. This pin serves as the primary supervised voltage input.
