HSOP TERMINAL DEFINITIONS
A functional description of each terminal can be found in the System/Application Information section, page 19.
Terminal
Terminal
Name
Formal Name
Definition
1
AGND
Analog Ground
Low-current analog signal ground.
2
FS
Fault Status for H-Bridge Open drain active LOW Fault Status output requiring a pullup resistor to 5.0 V.
3
IN1
Logic Input Control 1
Logic input control of OUT1 (i.e., IN1 logic HIGH = OUT1 HIGH).
4, 5, 16
V+
Positive Power Supply
Positive supply connections
6, 7
OUT1
H-Bridge Output 1
Output 1 of H-Bridge.
8
FB
Feedback for H-Bridge Current sensing feedback output providing ground referenced 1/375th (0.00266)
of H-Bridge high-side current.
9 – 12
PGND
Power Ground
High-current power ground.
13
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.
14, 15
OUT2
H-Bridge Output 2
Output 2 of H-Bridge.
17
CCP
Charge Pump Capacitor External reservoir capacitor connection for internal charge pump capacitor.
18
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.
19
IN2
Logic Input Control 2
Logic input control of OUT2 (i.e., IN2 logic HIGH = OUT2 HIGH).
20
Tab/Pad
EN
Thermal
Interface
Enable
Exposed Pad Thermal
Interface
Logic input Enable control of device (i.e., EN logic HIGH = full operation, EN logic
LOW = Sleep Mode).
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.
