Device Functional Modes (continued)

7.4.2 Low-Power Sleep Mode

The DRV887x family of devices support a low power mode to reduce current consumption from the VM pin when

the driver is not active. This mode is entered by setting the nSLEEP pin logic low and waiting for tSLEEP to elapse.

In sleep mode, the H-bridge, charge pump, internal 5-V regulator, and internal logic are disabled. The device

relies on a weak pulldown to ensure all of the internal MOSFETs remain disabled. The device will not respond to

any inputs besides nSLEEP while in low-power sleep mode.

7.4.3 Fault Mode

The DRV887x family of devices enter a fault mode when a fault is encountered. This is utilized to protect the

device and the output load. The device behavior in the fault mode is described in Table 7 and depends on the

fault condition. The device will leave the fault mode and re-enter the active mode when the recovery condition is

met.
