Abstract: In described examples, an integrated circuit comprising a first pin and a second pin. A switchable resistive element is coupled between the first pin and the second pin and has a pull down resistance state or a high resistance state. A comparator has a first comparator input coupled with the first pin, a reference signal input, and a comparator output. A logic circuit has an input coupled with the comparator output, an internal power good signal input, and a control signal output. The control signal output is coupled with the switchable resistive element to select the pull down resistance state or the high resistance state.

Abstract: A motor drive circuit includes a first serializer-deserializer (SER-DES) module that converts first SER-DES input signals into a first SER-DES output serial data stream. The first SER-DES input signals relate to motor control inputs or motor drive power outputs. A second SER-DES module converts a second SER-DES input serial data stream corresponding to the first SER-DES output serial data stream into second SER-DES output signals. The second SER-DES input signals relate to motor drive power outputs or motor control inputs. A serial isolation channel provides a galvanic isolation barrier between the first SER-DES module and the second SER-DES module. The serial isolation channel communicates the first SER-DES output serial data stream across the galvanic isolation barrier to provide the second SER-DES input serial data stream.
