PIN CONNECTIONS

Voltage Source 2

Sense input for the V2 regulator using an external series pass transistor. V2 is also the

internal supply for the CAN transceiver.

V2CTRL

Voltage Source 2 Control

Output drive source for the V2 regulator connected to the external series pass

transistor.

VSUP

Voltage Supply

Supply input pin for the 33742.

High-Side Output

Output of the internal high-side switch. The output current is internally limited to 150 mA.

30-33

L0-L3

Level 0-3 Inputs

Inputs from external switches or from logic circuitry.

CANH

CAN High Output

CAN high output pin.

CANL

CAN Low Output

CAN low output pin.
