Motor controller circuitry configured to operate two or more motors by driving the motors connected to output terminals of the motor controller circuitry. Each output terminal of the motor controller circuitry may connect to a driver circuit of the motor controller circuitry. Two, or more, of the motors may share an output terminal. For motors that share an output terminal, the operation of a first motor may affect the operation of other motors connected to that shared output terminal. The motor controller circuitry may store information about which output terminals may be paired, that is, which output terminals may connect to the same motor. Based on pairing information stored by the motor controller circuitry, protection circuitry of the motor controller circuitry may operate to prevent nuisance shutdown of a motor because the operation of another motor that shares the same output pin.

Pairing feature for driving DC motors with parallel capacitors in overcurrent recovery mode

This disclosure includes systems, methods, and techniques for controlling delivery of power to a load. For example, a circuit includes a first switching device and a second switching device. The circuit is configured to activate, in response to a source voltage of a semiconductor device being lower than a first voltage, the first switching device in order to cause the circuit to deliver a first electrical signal to the semiconductor device, where the first electrical signal includes the first voltage and deactivate the first switching device in response to the source voltage of the semiconductor device not being lower than the first voltage. Additionally, the circuit is configured to activate, in response to the source voltage of the semiconductor device not being lower than the first voltage, the second switching device to cause the circuit to deliver a second electrical signal to the semiconductor device.

Circuit for controlling a switching device to deliver power to a load

An electrostatic discharge clamp for groups of terminals having cascaded and different voltage classes, a plurality of discharge paths, and a multiple-input trigger circuit. In response to detecting a positive voltage event at any of the groups of terminals, the trigger circuitry can turn on an electronic switch causing current caused by the voltage event to flow through one or more of the discharge paths instead of through functional circuitry which could potentially be damaged by the current caused by the voltage event.
