APPLICATION INFORMATIONS
FORWARD REVERSE CONTROL LOGIC
FUNCTION Brake Reverse Forward Brake
load current flows from through motor. load current flows from through motor. KA8301 stops supplying power motor while absorbing counter from motor brake. RUSH CURRENT ABSORBING CIRCUIT high voltage generated during reversing operation applied across #10, internal comparator activates rush current absorbing circuit. DRIVE STAGE forward mode, drive stage supplies load current motor from #10. reverse mode, supplies current from output voltage(Vout) applied motor given followings where zener voltage applied VOUT VCE(sat), left open, output voltage given followings VOUT VCC1 VCE(sat, pnp) VCE(sat)
