It accepts a supply voltage from 8V to 14V and delivers a peak output current of 1A for both source and sink, with typical rise and fall times of 15 ns. The high-side bootstrap pin is rated to 108 V, setting the maximum DC bus voltage the driver can support. Operating over -40°C to 125°C, it suits industrial motor drives, DC-DC converters, and power supplies where the driver sits near the switching devices on the same PCB. ## 1 A peak drive — sizing the gate resistor and dead time With 1 A peak source and sink capability, this driver charges and discharges gate capacitance. The symmetric 15 ns rise and fall times simplify dead-time calculation. ## Lifecycle and sourcing — active, no LTB risk Texas Instruments lists the LM5109AMAX/NOPB as Active. For dual-sourcing, the LM5106MM/NOPB is a functional peer with similar half-bridge drive but synchronous channel type and slightly higher 1.2 A peak current — verify pin compatibility before substituting.","metaTitle":"LM5109AMAX/NOPB Half-Bridge Gate Driver, 1A Peak, 8-SOIC","metaDescription":"LM5109AMAX/NOPB half-bridge gate driver from TI. 8V–14V supply, 1A peak source/sink, 108V bootstrap, -40°C to 125°C.
