Formal Name
Definition
1
VDDQ
Logic Level Output Bias
Sets VOH level of DO output and LSCMP.
2
DO
SPI Data Out
SPI control data output pin from the IC to the MCU.
3
DI
SPI Data In
SPI control data input pin from the MCU to the IC.
4
SCLK
SPI Serial Clock Input
The SCLK input is the clock signal input for synchronization of serial data transfer.
5
CS
Chip Select
(Active Low)
This pin is an input connected to a chip select output of an MCU.
6
CRES
Charge Pump
This pin connects an external capacitor, which is the storage reservoir for the
internal charge pump.
7
REDIS
Automatic Output Re-
Enable Disable
This input pin is a connection to a capacitor that determines the default time the
output will be turned off when the low-side current comparator is tripped, if PWM
has not commanded it. The typical value with a 0.1
μF is 100μs. If shorted, the
feature is disabled.
8, 9, 22, 23
VIGNP
Protected Ignition
Voltage
This input pin is the primary H-Bridge power input.
Note: Not reverse voltage protected.
10, 11
S0
Bridge Output 0
to Load
These output pins drive the bi-directional motor and must be connected together
on the PC board.
12, 19
GND
Ground
These pins must be connected on the PC board to the exposed pad.
13, 17, 18
NC
No Connect
These pins have no internal connections.
14
LSCMP
Low Side Comparator
This output pin pulses high anytime the low side current comparator is tripped.
15
16
EN2
EN1
Master Enable 2
Master Enable 1
These input pins determine the mode of the IC; namely, sleep, standby, and run.
20, 21
S1
Bridge Output 1
to Load
These output pins drive the bi-directional motor and must be connected together
on the PC board.
