Abstract

Systems, apparatuses, and methods for charging a bootstrap capacitor of a device during low power states are described. In an example, an apparatus can include a controller configured to enable a low power state of the device. The device can include a high side switching element and a low side switching element. The controller can, in response to the low power state of the device being enabled, operate the low side switching element of the device to charge the bootstrap capacitor of the device. The controller can, in response to the low power state of the device being enabled and a level of a control signal being a first level, activate the low side switching element to charge the bootstrap capacitor of the device.
