It delivers 6 A peak output current across a 12 V to 25 V output supply range, with 5000 Vrms galvanic isolation. Typical deployment includes traction inverters, on-board chargers, and high-voltage DC-DC converters where the AEC-Q100 qualification and reinforced isolation are mandatory for the PPAP package. ## 6 A peak drive — what it means for IGBT and MOSFET selection The 6 A peak output current is the sourcing and sinking capability into the gate of a power switch. For a typical IGBT module with a gate charge of 1 µC, the ADUM4138WBRNZ-RL can switch it on in roughly 170 ns, assuming the 95 ns typical rise time. This matters for minimizing switching losses in hard-switched automotive inverters. The output supply range of 12 V to 25 V accommodates standard IGBT gate drive levels (typically 15 V) and allows headroom for desaturation protection circuits. ## 150 kV/µs CMTI — why it matters in switching power stages Common-mode transient immunity of 150 kV/µs (minimum) means the gate driver maintains its output state when a fast high-voltage transient slams across the isolation barrier. In a half-bridge inverter leg switching 600 V at 50 kHz, the dv/dt at the switch node can exceed 50 kV/µs. A driver with lower CMTI would glitch, causing shoot-through. The 150 kV/µs rating gives margin for even the fastest SiC and GaN transitions. ## Propagation delay and timing budget Maximum propagation delays are 130 ns (low-to-high) and 121 ns (high-to-low), with rise and fall times of 95 ns and 100 ns typical. These numbers define the minimum dead-time you can program in the controller without risking cross-conduction. For a 100 kHz switching frequency, the total delay plus rise/fall eats about 45 ns of each half-cycle, so the dead-time budget needs to account for the 130 ns max delay plus the 100 ns fall time. ## Lifecycle and compliance status It is ROHS3 compliant. For automotive OEM PPAP submissions, the AEC-Q100 qualification documentation is available from Analog Devices.","metaTitle":"ADUM4138WBRNZ-RL Automotive Gate Driver, 5000 Vrms, 6 A Peak","metaDescription":"ADUM4138WBRNZ-RL from Analog Devices: automotive-grade isolated gate driver, 5000 Vrms isolation, 6 A peak output, -40°C to 150°C.
