DESCRIPTION
The SiP42101 is a high-speed half-bridge MOSFET driver with
adaptive
applications. The high-side driver is bootstrapped to allow
driving n-channel MOSFETs. The Brake pin forces the lowside
MOSFET on, providing a braking function in H-bridge and
3-phase topologies.

The SiP42101 comes with adaptive shoot-through protection
to prevent simultaneous conduction of the external MOSFETs.
The SiP42101 is available in both standard and lead (Pb)-free
10-Pin MLP33 packages and is specified to operate over the
industrial temperature range of −40 _C to 85 _C.
