PD16813
MONOLITHIC DUAL H BRIDGE DRIVER CIRCUIT
DESCRIPTION
The
碌
PD16813 is a monolithic dual H bridge driver circuit which uses power MOS FETs in its driver stage. By
complementing the P channel and N channel of the output stage, the circuit current has been substantially inproved
as compared with that of conventional charge pump drivers.
The
碌
PD16813 is therefore ideal as the driver circuit of the 2-phase excitation, bipolar-driven stepping motor for
the head actuator of an FDD.
