Single low-side driver with 2A peak gate drive
The Texas Instruments TPS2816DBVT is a single-channel low-side gate driver designed to drive N-channel MOSFETs. It delivers 2A peak source and 2A peak sink current with 14ns typical rise and fall times, making it suitable for switching power supplies, DC-DC converters, and motor drive applications where fast gate charge and discharge are needed. The inverting input logic accepts standard logic levels with a 1V VIL and 4V VIH threshold, and the part operates from a 4V to 14V supply rail over the -40°C to 125°C temperature range.
14ns switching — what it buys the design
The 14ns rise and fall times are symmetric, which simplifies timing in half-bridge or synchronous rectifier stages where dead-time matching matters. At 2A peak drive, the TPS2816DBVT can fully charge a typical 10 nC gate charge in under 20 ns, keeping switching losses low in 100 kHz to 500 kHz converters. The inverting input means a logic high on the input turns the driver output low — check your PWM polarity before layout.
Supply range and logic compatibility
The 4V to 14V supply range covers standard 5V and 12V bias rails. The logic input thresholds — 1V VIL, 4V VIH — are compatible with 5V logic but will not reliably read a 3.3V logic-high as a valid high. If your controller runs on 3.3V, you need a level shifter or a different driver with lower VIH. The part is not compatible with 3.3V logic without an interface.
Package and storage note
Housed in a SOT-23-5 (SC-74A) surface-mount package, the TPS2816DBVT is a compact footprint for space-constrained designs. The part ships in Tape & Reel or Cut Tape options.
Lifecycle and sourcing
The TPS2816DBVT is listed as Active with ROHS3 compliance. For BOM planning, this means no immediate last-time-buy risk, and the part can be specified into new designs with confidence.
