Abstract:
Disclosed examples include isolated load switch driver circuits to drive a load, including an impedance circuit that receives a digital input voltage signal from a signal source, and selectively allows a current signal to flow from the signal source to charge a buffer capacitor. An impedance control circuit controls the impedance circuit to limit the current signal in response to the buffer capacitor reaching a first threshold voltage, and an output circuit provides an output isolated from the digital input voltage signal to switch the load. A signaling circuit selectively enables the output circuit to draw power from the buffer capacitor in response to the voltage of the buffer capacitor reaching the first threshold voltage.

Claim (Index 10):
An isolated load switch driver circuit, comprising:\n a signal input to receive a digital input voltage signal; an output circuit to provide a digital output voltage signal isolated from the digital input voltage signal; a buffer capacitor having a first terminal connected to a reference voltage and a second terminal; current limiter circuit, including first and second transistors connected in a back-to-back configuration between the signal input and the second terminal of the buffer capacitor; a first control circuit, including:\n a first output to provide a first signal to a control terminal of the first transistor to turn the first transistor on in response to the digital input voltage signal transitioning from the reference voltage to a second voltage, and \n a second output to provide a second signal to a control terminal of the second transistor to turn the second transistor on in response to the digital input voltage signal transitioning from the reference voltage to the second voltage until a voltage of the second terminal of the buffer capacitor reaches a first threshold voltage; and \n a second control circuit to provide a third signal to the control terminal of the second transistor to limit an amplitude of a current signal flowing from the signal input to the second terminal of the buffer capacitor in response to the voltage of the second terminal of the buffer capacitor reaching the first threshold voltage.
