Output
Output Current
Monitoring
This pin reports an analog value proportional to the designated HS[0:3] output
current or the temperature of the GND flag (pin 14). It is used externally to
generate a ground-referenced voltage for the microcontroller (MCU) . Current
recopy and temperature feedback is SPI programmable.

Input
Direct Inputs
Each direct input controls the device mode. The IN[0:3] high side input pins
are used to directly control HS0:HS3 high side output pins.
The PWM frequency can be generated from IN0 pin to PWM module in case
of external clock is set.

Output
Fault Status
(Active Low)
This pin is an open drain configured output requiring an external pull-up
resistor to VDD for fault reporting.
8
WAKE
Input
Wake
This input pin controls the device mode.
9
RST
Input
Reset
This input pin is used to initialize the device configuration and fault registers,
as well as place the device in a low-current Sleep mode.
10
CS
Input
Chip Select
(Active Low)
This input pin is connected to a chip select output of a master microcontroller
(MCU).
11
SCLK
Input
Serial Clock
This input pin is connected to the MCU providing the required bit shift clock for
SPI communication.
12
SI
Input
Serial Input
This pin is a command data input pin connected to the SPI serial data output
of the MCU or to the SO pin of the previous device of a daisy
-chain of devices.
13
VDD
Power
Digital Drain Voltage
This pin is an external voltage input pin used to supply power interfaces to the
SPI bus.
