Monitor Voltage Input 1–Monitor Voltage Input 8. Set monitor voltage range
through configuration registers. Measured value written to the ADC register
can be read back through the SMBus or JTAG interface.
6 6 CSP
Current-Sense Amplifier Positive Input. Connect CSP to the source side of the
external sense resistor.
7 7 CSM
Current-Sense Amplifier Negative Input. Connect CSM to the load side of the
external sense resistor.
8 8 RESET Configurable Reset Output
9 9 TMS JTAG Test Mode Select
10 10 TDI JTAG Test Data Input
11 11 TCK JTAG Test Clock
12 12 TDO JTAG Test Data Output
13 13 SDA SMBus Serial-Data Open-Drain Input/Output
14 14 A0 Four-State SMBus Address. Address sampled upon POR.
15 15 SCL SMBus Serial Clock Input
16, 33 16, 36 GND Ground
17, 18 — GPIO7, GPIO8
General-Purpose Input/Output 7 and General-Purpose Input/Output 8.
GPIO_s can be configured to act as a TTL input, a push-pull, open-drain, or
high-impedance output or a pulldown circuit during a fault event or reverse
sequencing.
19–24 17–22 GPIO1–GPIO6
General-Purpose Input/Output 1–General-Purpose Input/Output 6. GPIO_s
can be configured to act as a TTL input, a push-pull, open-drain, or high-
impedance output or a pulldown circuit during a fault event.

N.C. No Connection. Not internally connected.
28 29 EN
Analog Enable Input. All outputs deassert when V
EN
is below the enable
threshold.
30 31, 32 DBP
Digital Bypass. All push-pull outputs are referenced to DBP. Bypass DBP with
a 1FF capacitor to GND.
31 33, 34 V
CC
Device Power Supply. Connect V
CC
to a voltage from 2.8V to 14V. Bypass

Monitor Voltage Input 9–Monitor Voltage Input 12. Set monitor voltage range
through configuration registers. Measured value written to the ADC register
can be read back through the SMBus or JTAG interface.
— — EP
Exposed Pad. Internally connected to GND. Connect to ground, but do not
use as the main ground connection.
