Product Overview
MP1921HS-A-LF-Z is the RoHS tape-and-reel SOIC-8 orderable of MPS's MP1921A high-frequency half-bridge gate-driver family. It independently controls the high-side and low-side N-channel MOSFETs and integrates the bootstrap diode needed by the floating high-side driver.
The recommended VDD supply range is 9 V to 18 V. The 100 V / 120 V figures describe the switching-node and bootstrap domains, not a 100 V or 120 V logic-supply requirement. Typical propagation delay is 16 ns with less than 5 ns channel timing mismatch.

Engineering Selection Guidance
Keep VDD separate from the high-voltage domains: VDD is 9-18 V recommended, while the switch node is rated for operation up to 100 V and VBST has a higher absolute/range capability.
The 2.5 A headline is gate-drive capability and must not be interpreted as load or motor current.
The device is a driver for external N-channel MOSFETs; it does not integrate the half-bridge power switches.
HS-A-LF-Z identifies the SOIC-8, A-revision, RoHS tape-and-reel orderable.
Lifecycle and Ordering Context
MPS currently lists the relevant family/orderable context as Active. The exact MPN is MP1921HS-A-LF-Z in SOIC-8. Lifecycle information is for sourcing and design planning; it does not state HKEQGOO stock, lead time or delivery availability.
