8.3.2.1 PWM Control

The DRV8212P implements the same interface as the DRV8837/C devices for pin-to-pin replacement. The nSLEEP pin controls sleep mode. Table 8-2 shows the truth table for the PWM interface.

nSLEEP IN1 IN2 OUT1 OUT2 DESCRIPTION
0 X X Hi-Z Hi-Z Low-power sleep mode
1 0 0 Hi-Z Hi-Z Coast (H-bridge Hi-Z)
1 0 1 L H Reverse (OUT2 → OUT1)
1 1 0 H L Forward (OUT1 → OUT2)
1 1 1 L L Brake (low-side slow decay)
