7.4 Device Operational Modes

The DRV8262 supports dual or single H-bridge with PH/EN or PWM interface. The mode of operation is selected by the MODE1 and MODE2 pins as shown in Table 7-2.

  • The MODE1 and MODE2 pin states are latched when the device is enabled through the nSLEEP pin or at power-up.
  • The MODE2 pin has to be grounded to select PH/EN interface.
  • To select PWM interface, keep MODE2 pin floating or connect the MODE2 pin to DVDD.

The INx inputs can be set to static voltages for 100% duty cycle drive, or the INx inputs can be pulse-width modulated for variable motor speed. The input pins can be powered before VM supply is applied.

Section 7.4.1 and Section 7.4.2 show the truth tables for each interface. Note that the tables do not take into account the internal current regulation feature. Additionally, the DRV8262 automatically handles the dead time generation when switching between the high-side and low-side MOSFETs of a H-bridge.
