Description

1

VCC

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.

2

SENSE

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.

3

SETV

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.

4

GND

Chip Ground Pin.

5

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.

ADR

9

CLRB

Clear Pin. A latched overcurrent condition can be cleared by pulling this pin low.

10

ALERT

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.
