NOTES:
1. The system bandwidth is fixed by an internal RC network around the amplifier.
2. Internal limiting of turn on and turn off drive is used to limit output dv/dt.
3. The braking action starts at the given trip point with a falling supply voltage.
4. Hysteresis causes the brake to be removed at a higher trip point with a rising supply voltage.
5. This value includes the combined voltage drops of one upper plus one lower switch at the indicated current.
