The TPIC1505 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.

The TPIC1505 is offered in a 24-pin wide-body surface-mount (DW) package and is characterized for operation
over the case temperature range of –40°C to 125°C.
