NAME
FUNCTION
ALERT
SMBus Alert Open-Drain Output. ALERT follows the SMBALERT# signal functionality
described in Appendix A of the SMBus 2.0 Specification. ALERT asserts when the device
detects a fault, thereby interrupting the host processor to query which device on the serial
bus detected faults.
OVERT ^{Overtemperature, Open-Drain Output. OVERT asserts when an overtemperature condition is}
detected.
OVERC ^{Overcurrent, Open-Drain Output. OVERC asserts when the primary overcurrent threshold is}
exceeded.

TMS JTAG Test Mode Select Input. Internally pulled up to VDBP with a 10kΩ resistor.
TCK JTAG Test Clock Input
TDI JTAG Test Data Input. Internally pulled up to VDBP with a 10kΩ resistor.
TDO JTAG Test Data Output
DBP
Internal Digital Voltage Regulator Output. Connect a 1µF bypass capacitor from DBP to
GND. Do not use DBP to power external circuitry.

IN1
Internal Analog Voltage Regulator Output. Connect a 1µF bypass capacitor from ABP to
GND. Do not use ABP to power external circuitry.
Device Power Supply. Bypass VCC to GND with a 1µF capacitor.
Current-Sense Negative Input. Must be biased between 3V to 28V for proper operation.
Current-Sense Positive Input. Must be biased between 3V to 28V for proper operation.
Remote Diode 2 Negative Input. If remote sensing is not used, connect DXP2 to DXN2.
Remote Diode 2 Positive Input. If remote sensing is not used, connect DXP2 to DXN2.
Remote Diode 1 Negative Input. If remote sensing is not used, connect DXP1 to DXN1.
Remote Diode 1 Positive Input. If remote sensing is not used, connect DXP1 to DXN1.
Supply Monitor Input 1. IN1 is internally sampled by the ADC. It is configurable for unipolar/
bipolar and single-ended/pseudo-differential. In pseudo-differential mode, IN1 and IN2 form
the + and - of the differential pair. Each input must stay within the specified ADC IN_ voltage
range.
EP
Exposed Paddle. Connect EP to ground. EP is internally connected to GND. Do not use as
the main ground connection.
