Description
Positive Supply Input Pin. The operating supply voltage range is from 3.15 V to 16.5 V. An undervoltage
lockout (UVLO) circuit resets the ADM1175 when a low supply voltage is detected.
Current Sense Input Pin. A sense resistor between the VCC pin and the SENSE pin sets the analog current
limit. The hot swap operation of the ADM1175 controls the external FET gate to maintain the (V CC ? V SENSE )
voltage at or below 100 mV.
Undervoltage or Overvoltage Input Pin. This pin is active high on the ADM1175-1 and ADM1175-2 and
active low on the ADM1175-3 and ADM1175-4. An internal undervoltage comparator has a trip threshold of
1.3 V, and the output of this comparator is used as an enable for the hot swap operation. For the ON pin
variants with an external resistor divider from VCC to GND, this pin can be used to enable the hot swap
operation for a specific voltage on VCC, providing an undervoltage function. Similarly, for the ONB pin
variants, an external resistor divider can be used to create an overvoltage function, where the divider sets a
voltage on VCC, at which the hot swap operation is switched off, pulling the GATE to ground.
Chip Ground Pin.
Timer Pin. An external capacitor, C TIMER , sets a 270 ms/μF initial timing cycle delay and a 21.7 ms/μF fault delay.
The GATE pin turns off when the TIMER pin is pulled beyond the upper threshold. An overvoltage detection
with an external Zener can be used to force this pin high.
I 2 C Clock Pin. Open-drain input requires an external resistive pull-up.
I 2 C Data I/O Pin. Open-drain input/output. Requires an external resistive pull-up.
I 2 C Address Pin. This pin can be tied low, tied high, left floating, or tied low through a resistor to set four
different I 2 C addresses.
Convert Start Pin. A high level on this pin enables an ADC conversion. The state of an internal control register,
which is set through the I 2 C interface, configures the part to convert current only, voltage only, or both
channels when the convert pin is asserted. This pin must be pulled high to allow conversions to take place.
GATE Output Pin. This pin is the high-side gate drive of an external N-channel FET. This pin is driven by the
FET drive controller, which utilizes a charge pump to provide a 12.5 μA pull-up current to charge the FET
GATE pin. The FET drive controller regulates to a maximum load current (100 mV through the sense resistor)
by modulating the GATE pin.
