2.1 Power Connectors

This EVM offers access to the Motor Voltage (VM) power rail via a terminal block (J3). A set of test clips in

parallel with the terminal block allows monitoring of the input power rail.

Since the DRV8844 can be utilized with either split power supplies (+VM/-VM) or with a single power

supply (+VM), jumper JP2 allows the LGND and –VM nodes to be connected together when using the

single power-supply implementation.

The VM must be applied according to the parameters recommended in the DRV8844 datasheet

(SLVSBA2 ).

2.2 Test Stakes

Test stakes surrounding the DRV8844 allow access to monitoring all control and output signals.
