description
The TPIC1501A is a monolithic power array that
consists of ten electrically isolated N-channel
enhancement-mode power DMOS transistors, four
of which are configured as a full H-bridge and six as
a triple half H-bridge. The lower stage of the full
H-bridge features an integrated sense FET to allow
biasing of the bridge in class A-B operation.
