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 1):
An integrated circuit (IC), comprising:\n a first input pin having a reference voltage; a second input pin to receive a digital input voltage signal having a first voltage relative to the reference voltage in a first state, and a different second voltage relative to the reference voltage in a second state; a current limiter circuit, including:\n an impedance circuit, including an input connected to the second input pin, and an output to deliver a current signal to a buffer capacitor, the impedance circuit operative in a first mode to connect the second input pin to the buffer capacitor, and in a second mode to provide a controlled impedance between the second input pin and the buffer capacitor to limit an amplitude of the current signal, \n a precharge circuit to provide a first signal in response to a supply voltage across the buffer capacitor reaching a first threshold voltage, and \n an impedance connection control circuit to switch the impedance circuit from the first mode to the second mode in response to the first signal; \n an output circuit, including an input connected to the buffer capacitor to receive the supply voltage, and an output isolated from the supply voltage, the output being connected to third and fourth pins of the IC; and a control circuit, including an output to provide an enable signal in response to the first signal to enable the output circuit to selectively provide a voltage output signal to the third and fourth pins.
