DESCRIPTION
Logic ground
Current limit control
Connect to board ground
Connect a resistor to ground to set the current chopping threshold
Logic inputs
Controls the H-bridge output. Has internal pulldowns. (See Table 1.)

H-bridge output
Connect directly to the motor or other inductive load.

High-current ground path
6.5-V to 45-V power
supply
Connect to board ground. For good thermal dissipation, use large
ground planes on multiple layers, and multiple nearby vias
connecting those planes.
Connect to board ground.
Connect a 0.1-µF bypass capacitor to ground, as well as sufficient
bulk capacitance, rated for the VM voltage.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
6.2 ESD Ratings

(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
