Definition

GND

VDD

Digital ground.

Logic supply voltage. Logic supply must be switched off for low current mode (V_DDbelow 3.9 V).

3, 4

Output 8 MOSFET source pins.

Output 8 MOSFETdrain pin.

Output 2 MOSFET source pin.

Output 2 MOSFET drain pin.

8, 9, 24, 25

TGND

Thermal Ground pins are connected internally to the substrate of the die and are used for heat transfer.

Connect thermal ground pins to the PCB ground and ground plane for heat sinking.

Output 1 MOSFET source pin.

Output 1 MOSFET drain pin.

Output 6 MOSFETdrain pin.

Output 6 MOSFET source pin.

IN6

PWM direct control input pin for output 6. IN6 is “OR” with SPI bit.

Enable input. Allows control of outputs. Active high.

SPI control clock input pin.

SCLK

SPI control data input pin from MCU to the 33880. Logic [1] activates output.

SPI control chip select input pin from MCU to the 33880. Logic [0] allows data to be transferred in.

PWM direct control input pin for output 5. IN5 is “OR” with SPI bit.

Output 5 MOSFET source pin.

IN5

Output 5 MOSFET drain pin.

Output 3 MOSFET drain pin.

Output 3 MOSFET source pin.

Output 4 MOSFET drain pin.

Output 4 MOSFET source pin.

Output 7 MOSFET drain pin.

29, 30

Output 7 MOSFET source pins.

VPWR

Power supply pin to the 33880. VPWR has internal reverse battery protection.

SPI control data output pin from the 33880 to the MCU. DO = 0 no fault, DO = 1 specific output has fault.
