Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

Table 4. Pin Function Descriptions
Pin No. Mnemonic Description
1 TIMER Timer Input Pin. The initial and circuit breaker timing cycles are set by this external capacitor. The initial timing
delay is 272.9 ms/μF, and 21.7 ms/µF for a circuit breaker delay. When the TIMER pin is pulled beyond the upper
threshold, the GATE turns off.
2 GND Chip Ground Pin.
3
ON (ON-
CLR
)
Input Pin. The ON (ON-
CLR
) pin is an input to a comparator that has a low-to-high threshold of 1.3 V with 80 mV
hysteresis and a glitch filter. The ADM4210 is reset when the ON (ON-
CLR
) pin is low. When the ON (ON-
CLR
) pin is
high, the
ADM4210 is enabled. A rising edge on this pin has the added function of clearing a fault and restarting
the device on the latched off model, the ADM4210-2.
4 GATE Gate Output Pin. An internal charge pump provides a 12 µA pull-up current to drive the gate of an N-channel
MOSFET. In an overcurrent condition, the ADM4210 controls the external FET to maintain a constant load
current.
5 SENSE Current Limit Sense Input Pin. The current limit is set via a sense resistor between the V
CC
and SENSE pins. In an
overcurrent condition, the gate of the FET is controlled to maintain the SENSE voltage at 50 mV. When this limit is
reached, the TIMER circuit breaker mode is activated. The circuit breaker limit can be disabled by connecting the
V
CC
pin and SENSE pin together.
6 V
CC
Positive Supply Input Pin. The ADM4210 operates between 2.7 V to 16.5 V. An undervoltage lockout (UVLO)
circuit with a glitch filter resets the ADM4210 when the supply voltage drops below the specified UVLO limit.
