Description
Positive Supply Input Pin. The operating supply voltage range is 3.15 V to 26 V. An undervoltage lockout
(UVLO) circuit resets the ADM1192 when a low supply voltage is detected.
Current Sense Input Pin. A sense resistor between the VCC pin and the SENSE pin generates a voltage across
a sense resistor. This voltage is proportional to the load current. A current sense amplifier amplifies this
voltage before it is digitized by the ADC.
Input Pin. The voltage driven onto this pin is compared to the output of the internal current sense amplifier.
The lower the voltage on the SETV, the lower the current level that causes the ALERT output to assert.
Chip Ground Pin.
Timer Input Pin. An external capacitor, C
TIMER
,
sets the timing period for masking overcurrent conditions. This
timing period should be sufficient to allow the load charge up completely with maximum current at startup
without tripping an overcurrent fault.

C Address Pin. This pin can be tied low, tied high, left floating, or tied low through a resistor to set four
different I

C addresses.
Clear Pin. A latched overcurrent condition can be cleared by pulling this pin low.
Alert Output Pin. Active high, open-drain configuration. This pin asserts high when an overcurrent condition
is present. The level at which an overcurrent condition is detected depends on the voltage on the SETV pin.
