Name
Type
Function
17
VDD
Power
Logic outputs supply voltage (pull-up reference)
6
VREG
Power
Internal 3 V voltage regulator output and 3.3 V external
logic supply
7
OSCIN
Analog input
Oscillator pin 1. To connect an external oscillator or clock
source. If this pin is UNUSED, it should be connected to
ground.
8
OSCOUT
Analog output
Oscillator pin 2. To connect an external oscillator. When
the internal oscillator is used this pin can supply a
2/4/8/16 MHz. If this pin is UNUSED, it should be left
floating.

CP
Output
Charge pump oscillator output
11
VBOOT
Supply voltage
Bootstrap voltage needed for driving the high side power
DMOS of both bridges (A and B)
5
ADCIN
Analog input
Internal analog to digital converter input
