Abstract

The present disclosure provides a multi-channel actuator for driving a low side device. In some implementations, the actuator includes a controller that receives a first command for driving a low-side device and outputs data representative of the first command. The actuator includes a drive circuit having a plurality of detection and drive stages. The plurality of detection stages and driver stages may be coupled with the plurality of channels of the low-side device, respectively. The drive circuit receives data representative of a first command and causes a detection and drive stage of the plurality of detection and drive stages to drive a corresponding channel of the low-side device in accordance with the first command.
