Pin Functions

PIN TYPE DESCRIPTION
NAME NO.
AIN1 16 I Bridge A input 1 Controls AOUT1; tri-level input
AIN2 15 I Bridge A input 2 Controls AOUT2; tri-level input
AISEN 3 O Winding A sense Connect to current sense resistor for bridge A, or GND if current regulation is not required
AOUT1 2 O Winding A output
AOUT2 4
BIN1 9 I Bridge B input 1 Controls BOUT1; internal pulldown
BIN2 10 I Bridge B input 2 Controls BOUT2; internal pulldown
BISEN 6 O Winding B sense Connect to current sense resistor for bridge A, or GND if current regulation is not required
BOUT1 7 O Winding B output
BOUT2 5
GND 13 PWR Device ground Both the GND pin and device PowerPAD must be connected to ground
PPAD
nFAULT 8 OD Fault indication pin Pulled logic low with fault condition; open-drain output requires external pullup
nSLEEP 1 I Sleep mode input Logic high to enable device; logic low to enter low-power sleep mode; internal pulldown
VINT 14 — Internal regulator Internal supply voltage; bypass to GND with 2.2-μF, 6.3-V capacitor
VM 12 PWR Power supply Connect to motor power supply; bypass to GND with a 0.1- and 10-μF (minimum) ceramic capacitor rated for VM
VREF 11 I Full-scale current reference input Voltage on this pin sets the full scale chopping current; short to VINT if not supplying an external reference voltage

External Components

COMPONENT PIN 1 PIN 2 RECOMMENDED
CVM VM GND 10-µF (minimum) ceramic capacitor rated for VM
CVM VM GND 0.1-µF ceramic capacitor rated for VM
CVINT VINT GND 6.3-V, 2.2-µF ceramic capacitor
RnFAULT VCC(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) VCC is not a pin on the DRV8848, but a VCC supply voltage pullup is required for open-drain output nFAULT; nFAULT may be pulled up to VINT
