Half-bridge driver with 2A peak gate drive — what it does
The MAX5064BATC+T is a half-bridge gate driver from Analog Devices (formerly Maxim Integrated) designed to drive two N-channel MOSFETs in a half-bridge configuration. It delivers 2A peak source and 2A peak sink current, which gives you the muscle to charge and discharge large gate capacitances quickly — useful for keeping switching losses low in DC-DC converters, motor-drive inverters, and synchronous rectifier stages. The bootstrap supply is rated to 125 V, so it handles 48 V and 72 V bus rails with margin, and the independent inverting and non-inverting input channels let you wire the dead-time logic however your controller expects it.
125 V bootstrap — what that means for your bus voltage
The 125 V maximum high-side voltage (bootstrap) sets the absolute ceiling for the floating supply that powers the high-side driver. If your half-bridge DC bus sits at 48 V or even 72 V nominal, you have healthy headroom. The 8 V to 12.6 V supply range on the low side is typical for biasing the driver core and gate-drive rails; stay inside that window or the UVLO may not release cleanly.
Temperature range and package — where it fits
Rated for -40°C to 150°C junction temperature, so this driver is comfortable in under-hood automotive, industrial motor drives, and outdoor telecom equipment where ambient heat is a given. The 12-WQFN with exposed pad (4x4 mm) needs a thermal via array under the paddle to pull heat into the PCB ground plane — without it, the junction temp rises fast when you push 2 A gate-drive pulses at high frequency.
Lifecycle and sourcing
Marked as Active in the product lifecycle, so no LTB risk for new designs. ROHS3 compliant. No pin-compatible second source is listed in the official cross-reference, so you are single-sourced on the die — plan your buffer stock accordingly.
