Pin Functions

PIN TYPE DESCRIPTION
NAME PWP RTE
POWER AND GROUND
GND 13 11 PWR Device ground Both the GND pin and device PowerPAD must be connected to ground
VINT 14 12 — Internal regulator (3.3 V) Internal supply voltage; bypass to GND with 2.2-μF, 6.3-V capacitor
VM 12 10 PWR Power supply Connect to motor supply voltage; bypass to GND with a 10-µF (minimum) capacitor rated for VM
CONTROL
AIN1 16 14 I H-bridge A PWM input Controls the state of AOUT1 and AOUT2; internal pulldown
AIN2 15 13
BIN1 9 7 I H-bridge B PWM input Controls the state of BOUT1 and BOUT2; internal pulldown
BIN2 10 8
nSLEEP 1 15 I Sleep mode input Logic high to enable device; logic low to enter low-power sleep mode; internal pulldown
STATUS
nFAULT 8 6 OD Fault indication pin Pulled logic low with fault condition; open-drain output requires an external pullup
OUTPUT
AISEN 3 1 O Bridge A sense Sense resistor to GND sets PWM current regulation level (seePWM Motor Drivers)
AOUT1 2 16 O Bridge A output Positive current is AOUT1 → AOUT2
AOUT2 4 2
BISEN 6 4 O Bridge B sense Sense resistor to GND sets PWM current regulation level (see PWM Motor Drivers)
BOUT1 7 5 O Bridge B output Positive current is BOUT1 → BOUT2
BOUT2 5 3

External Components

Component Pin 1 Pin 2 Recommended
CVM VM GND 10-µF(2) ceramic capacitor rated for VM
CVINT VINT GND 6.3-V, 2.2-µF ceramic capacitor
RnFAULT VINT(1) nFAULT >1 kΩ
RAISEN AISEN GND Sense resistor, see Typical Application for sizing
RBISEN BISEN GND Sense resistor, see Typical Application for sizing
(1) nFAULT may be pulled up to an external supply rated < 5.5 V.
(2) Proper bulk capacitance sizing depends on the motor power.
