Low-current analog signal ground.
Open drain active LOW Fault Status output requiring a pull-up resistor to
5.0 V.
Logic input control of OUT1 (i.e., IN1 logic HIGH = OUT1 HIGH).
Positive supply connections
Output 1 of H-Bridge.
Current sensing feedback output providing ground referenced 1/375th
(0.00266) of H-Bridge high-side current.
High-current power ground.
Active LOW input used to simultaneously tri-state disable both H-Bridge
outputs. When D2 is Logic LOW, both outputs are tri-stated.
Output 2 of H-Bridge.
External reservoir capacitor connection for internal charge pump capacitor.
Active HIGH input used to simultaneously tri-state disable both H-Bridge
outputs. When D1 is Logic HIGH, both outputs are tri-stated.
Logic input control of OUT2 (i.e., IN2 logic HIGH = OUT2 HIGH).
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.
