Definition
1–4, 51–54
PGND
Power Ground
High-current power ground.
5–7, 9, 14, 19–22,
27– 29, 33–36, 41,
46, 48–50
NC
No Connect
No internal connection to this terminal.
8
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.
10–13
OUT2
H-Bridge Output 2
Output 2 of H-Bridge.
15 –18, 37–40
V+
Positive Power Supply
Positive supply connections.
23
CCP
Charge Pump Capacitor
External reservoir capacitor connection for internal charge pump
capacitor.
24
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.
25
IN2
Logic Input Control 2
Logic input control of OUT2 (i.e., IN2 logic HIGH = OUT2 HIGH).
26
EN
Enable
Logic input Enable control of device (i.e., EN logic HIGH = full operation,
EN logic LOW = Sleep Mode).
30
AGND
Analog Ground
Low-current analog signal ground.
31
FS
Fault Status for H-Bridge
Open drain active LOW Fault Status output requiring a pull-up resistor to
5.0 V.
