Driving VADJ Via Open Collector Transistor The VADJ can also be driven via an open collector transistor as shown below. The diode and resistor serve to suppress any possible high amplitude negative voltage spikes to the VADJ input result ing from the collector to emitter capacitance of the transistor. Any negative voltage spikes will cause errors in output current and/or unstable driver operation. Driving the VADJ from a Microcontroller The VADJ can be driven from an open drain output of a microcontroller as shown below. The diode and resistor serve to suppress any possible high amplitude negative voltage spikes to the VADJ input resulting from the drain to source capacitance of the FET. Any negative voltage spikes will cause errors in output current and/or unstable driver operation.
