NC
No Connect
No internal connection to this terminal.
2
D1
Disable 1
Active HIGH input used to simultaneously tri-state disable both H-Bridge
outputs. When D1 is Logic HIGH, both outputs are tri-stated.
3
IN2
Logic Input Control 2
Logic input control of OUT2 (i.e., IN2 logic HIGH = OUT2 HIGH).
4
EN
Enable
Logic input Enable control of device (i.e., EN logic HIGH = full operation,
EN logic LOW = Sleep Mode).
5, 6, 12, 13, 34, 35
V+
Positive Power Supply
Positive supply connections.
8
AGND
Analog Ground
Low-current analog signal ground.
9
FS
Fault Status for H-Bridge
Open drain active LOW Fault Status output requiring a pull-up resistor to
5.0 V.
11
IN1
Logic Input Control 1
Logic input control of OUT1 (i.e., IN1 logic HIGH = OUT1 HIGH).
14, 15, 17, 18
OUT1
H-Bridge Output 1
Output 1 of H-Bridge.
20
FB
Feedback for H-Bridge
Current feedback output providing ground referenced 1/375th ratio of
H-Bridge high-side current.
21–26
PGND
Power Ground
High-current power ground.
27
D2
Disable 2
Active LOW input used to simultaneously tri-state disable both H-Bridge
outputs. When D2 is Logic LOW, both outputs are tri-stated.
29, 30, 32, 33
OUT2
H-Bridge Output 2
Output 2 of H-Bridge.
36
C
CP
Charge Pump Capacitor
External reservoir capacitor connection for internal charge pump capacitor.
Tab/Pad
Thermal
Interface
Exposed Pad Thermal
Interface
Exposed pad thermal interface for sinking heat from the device.
Note
Must be DC-coupled to Analog ground and Power ground via very low
impedance path to prevent injection of spurious signals into IC substrate.
