PRODUCTION DATA
When the MODE pin is logic high on power up, the device selects "phase-enable" mode (PH/EN). PH/EN mode allows for the H-bridge to be controlled with a speed and direction type of interface. Table 8-4 shows the truth table for PH/EN mode. When the EN pin is low, the device enters brake mode. This allows the controller to use a single PWM generator peripheral on the EN pin while a standard GPIO pin controls directions using the PH pin. However, if the EN pin remains low for longer than tSLEEP, the device goes into low-power sleep mode and the outputs are disabled.
EN | PH | OUT1 | OUT2 | DESCRIPTION |
---|---|---|---|---|
0 | X | L → Hi-Z | L → Hi-Z | Brake (low-side slow decay) for tSLEEP, then auto-sleep mode (H-bridge Hi-Z) |
1 | 0 | L | H | Reverse (OUT2 → OUT1) |
1 | 1 | H | L | Forward (OUT1 → OUT2) |
