Pin No.
Mnemonic
Description
12, 13
REXT2, REXT1
A 15 k external current setting resistor can be connected between the REXT1 and REXT2 pins to
improve the IOUT temperature drift performance.
14
VREF
Buffered Reference Input.
15
VIN
Buffered Analog Input (0 V to 4.096 V).
16
GND
Ground Connection.
17
AVDD
Positive Analog Supply.
18
IOUT
Current Output.
19, 20, 23, 24
DNC
Do not connect to these pins.
21, 22
GND
Ground Connection.
25, 26, 27, 28
NC
No Connect. Can be tied to GND.
29
HW SELECT
This part is used to configure the part to hardware or software mode.
HW SELECT = 0 selects software control.
HW SELECT = 1 selects hardware control.
30
RESET
In software mode, this pin resets the part to its power-on state. Active low.
In hardware mode, there is no reset. If using the part in hardware mode, the RESET pin should be tied high.
31
FAULT/TEMP
Fault Alert (FAULT). In software mode, this pin acts as a general fault alert pin. It is asserted low when an
open-circuit, overtemperature error, or PEC interface error is detected. This pin is an open-drain output
and must be connected to a pull-up resistor.
Overtemperature Fault (TEMP). In hardware mode, this pin acts as an overtemperature fault pin. It is
asserted low when an overtemperature error is detected. This pin is an open-drain output and must be
connected to a pull-up resistor.
32
NC/IFAULT
No Connect (NC). In software mode, this pin is a no connect. Instead, tie this pin to GND.
Open-Circuit Fault Alert (IFAULT). In hardware mode, this pin acts as an open-circuit fault alert pin. It is
asserted low when an open-circuit error is detected. This pin is an open-drain output and must be
connected to a pull-up resistor.
33 (EPAD)
EPAD
The exposed paddle is tied to GND.
