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 pullup 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.
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.
