Device Overview
MP8699BGC-Z is a 100 V-capable half-bridge gate driver for enhancement-mode GaN MOSFETs and low-gate-voltage N-channel MOSFETs. It uses independent high-side and low-side PWM inputs and operates from a 4.5 V to 5.5 V VCC supply.
MPS specifies a typical 17 ns propagation time and 1.5 ns typical propagation-delay matching. Separate gate outputs allow different impedances to be used for turn-on and turn-off, with a 0.2 ohm pull-down path and 1.3 ohm pull-up path listed in the datasheet.

Engineering Selection Guidance
The 100 V figure applies to the floating high-side bias rail, not to the low-voltage VCC pin. VCC remains in the 4.5-5.5 V range, while the bootstrap/high-side structure supports the elevated switching node.
The 17 ns propagation time and 1.5 ns delay matching are typical values. They should be used as timing-characterization points rather than rewritten as unconditional maximum guarantees. Dead-time design still needs the full timing table and MOSFET switching behavior.
MPS’s bootstrap scheme limits the high-side gate drive so the GaN gate is not overdriven above VCC. The exact GC-Z orderable uses a compact WLCSP-12L (2 mm x 2 mm), making PCB parasitics and assembly constraints especially important.
