Slow demagnetization

Applies to C/Q channel.

Slow demagnetization schematic block. Load connected to L-

When a high-side driver turns off an inductance a reversed polarity voltage appears across

the load.

In slow demagnetization configuration the low-side switch Q2 is ON and the C/Q pin is

pulled at a voltage slightly (depending on Q2 drop) below the ground (L-). The energy is

dissipated in both the IC internal switch and the load resistance.

In the case of load connected between the C/Q pin and VCC, at switch-off (of the low-side

switch Q2), the switch Q1 is ON and the output is pushed to a voltage slightly higher than

VCC.
