LS2

Low Side Output 2

Low Side output 2 used to drive small inductive loads like relays. The output is 
short-circuit protected, includes active clamp circuitry and can be also controlled by 
the PWM module.

ISENSEL

Current Sense Pins L

Current Sense differential input “Low”. This pin is used in combination with 
ISENSEH to measure the voltage drop across a shunt resistor. See 

. Note: This pin function is not available on all 

device configurations.

41

ISENSEH

Current Sense Pins H

Current Sense differential input “High”. This pin is used in combination with 
ISENSEL to measure the voltage drop across a shunt resistor. 

. Note: This pin function is not available on all 

device configurations.

42

NC

Not connected Pin

This pin is reserved for alternative function and should be left floating.

43

TEST_A

Test Mode Pin

Analog die Test Mode pin for Test Mode only. This pin must be grounded in user 
mode.

44

TCLK

Test Clock Input

Test Mode Clock Input pin for Test Mode only. The pin can be used to disable the 
internal watchdog for development purpose in user mode. See 

. The pin is recommended to be grounded in user mode.

45

RESET_A

 Reset I/O

Bidirectional Reset I/O pin of the analog die. Active low signal. Internal pull-up. V

based. See 

. To be externally connected to the RESET pin.

46

RESET

MCU Reset Pin

The RESET pin is an active low bidirectional control signal. It acts as an input to 
initialize the MCU to a known start-up state, and an output when an internal MCU 
function causes a reset. The RESET pin has an internal pull-up device to EVDDX.

47

BKGD

MCU Background Debug 
and Mode Pin

The BKGD/MODC pin is used as a pseudo-open-drain pin for the background 
debug communication. It is used as MCU operating mode select pin during reset. 
The state of this pin is latched to the MODC bit at the rising edge of RESET. The 
BKGD pin has a pull-up device.

48

NC

Not connected Pin

This pin is reserved for alternative function and should be left floating or connected 
to GND.

Note:

4. An optional filter capacitor C

VSENSE

 is recommended to be placed between the board connector and R

VSENSE

 to GND for increased ESD 

performance.

5. An optional filter capacitor C

Lx

 is recommended to be placed between the board connector and R

Lx

 to GND for increased ESD 

performance.
