Abstract
According to certain aspects, a driver includes an output transistor coupled between a first rail and an output of the driver, a first current source coupled to a gate of the output transistor, a second current source, and a switch, wherein the switch and the second current source are coupled in series between the gate of the output transistor and a second rail. The driver also includes a current sensor configured to generate a sense current based on an output current of the driver, and a reference current source configured to generate a reference current, wherein the current sensor and the reference current source are coupled to a control input of the switch.
