Name Type Function
HTSSOP POWERSO
17 24 VDD Power Logic outputs supply voltage (pull-up reference)
6 9 VREG Power
Internal 3 V voltage regulator output and 3.3 V
external logic supply
7 10 OSCIN Analog input
Oscillator pin 1. To connect an external oscillator or
clock source. If this pin is unused, it should be left
floating.
8 11 OSCOUT Analog output
Oscillator pin 2. To connect an external oscillator.
When the internal oscillator is used this pin can
supply 2/4/8/16 MHz. If this pin is unused, it should be
left floating.
10 13 CP Output Charge pump oscillator output
11 14 VBOOT Supply voltage
Bootstrap voltage needed for driving the high-side
power DMOS of both bridges (A and B)
5 8 ADCIN Analog input Internal analog-to-digital converter input
2, 26 4, 5, 33, 34 VSA Power supply
Full bridge A power supply pin. It must be connected
to VSB.
12, 16 15, 16, 22, 23 VSB Power supply
Full bridge B power supply pin. It must be connected
to VSA.
27, 13 1, 19 PGND Ground Power ground pin
1 2, 3 OUT1A Power output Full bridge A output 1
28 35, 36 OUT2A Power output Full bridge A output 2
14 17, 18 OUT1B Power output Full bridge B output 1
15 20, 21 OUT2B Power output Full bridge B output 2
9 12 AGND Ground Analog ground.
4 7 SW Logical input
External switch input pin. If not used the pin should be
connected to VDD.
21 28 DGND Ground Digital ground
22 29 BUSY
\SYNC Open drain output
By default, this BUSY pin is forced low when the
device is performing a command. Otherwise the pin
can be configured to generate a synchronization
signal.
18 25 SDO Logic output Data output pin for serial interface
20 27 SDI Logic input Data input pin for serial interface
19 26 CK Logic input Serial interface clock
23 30 CS
Logic input Chip select input pin for serial interface
