H-bridge drive. In addition to the h-bridge driver specifications given in Table B61, the parameters in Table B62 must also be specified. See Figure B37.
Figure B37: Discrete output, h-bridge.
The protection components D1 and C1 must be suitable and designed to protect the used MOSFET and MOSFET drive. When the load energy is suddenly out of control in the off state, it will be released due to overvoltage or overcurrent triggering.
