Abstract
A driver coupled to a configurable load having a first load portion coupled to a second load portion at an intermediate node includes a first switch coupled to the intermediate node and to a battery voltage, and a second switch coupled to the second load portion and ground. A current steering control circuit of the driver is responsive to a feedback voltage associated with the intermediate node and is configured to generate a first switch control signal and a second switch control signal to control a slew rate of either the first switch or the second switch. The current steering control circuit can include a gate driver and a current steering amplifier.
