Abstract
An inductive load driver circuit with shared flyback protection includes a first transistor (209) which drives a first load (229), and a second transistor (231) drives a second load (251). A first clamp voltage steering diode (217) is coupled between an input terminal (207) of the first transistor (209) and a zener diode (203), and a second clamp voltage steering diode (239) coupled between an input terminal (233) of the second transistor (231) and the zener diode (203). A power supply terminal (201) is coupled to the zener diode (203).
