Drive strength for automotive IGBTs and MOSFETs
The UCC27519AQDBVRQ1 delivers 4 A peak source and 4 A peak sink current, enough to drive the gate capacitance of a large IGBT or N-channel MOSFET without excessive Miller plateau dwell time. In a 10 nC gate-charge load, the 8 ns rise and 7 ns fall typ edges keep switching losses low enough that the thermal budget stays under the 150°C junction limit.
AEC-Q100 grade and temperature envelope
This part carries AEC-Q100 qualification and operates across -40°C to 150°C junction temperature. That 150°C TJ ceiling is what separates an underhood-capable driver from a cabin-only one — the OEM auditor will ask for the PPAP documentation confirming the grade-1 classification. Lifecycle status is active, so no last-time-buy scramble for ongoing production builds.
SOT-23-5 footprint and supply rail tolerance
The SOT-23-5 package occupies minimal PCB area — useful when the gate driver sits close to the power switch to minimise gate-loop inductance. Input is non-inverting, so the PWM polarity matches the controller output without an extra inverter gate.
Sourcing and compliance posture
The base product number is UCC27519; the suffix QDBVRQ1 identifies the automotive-qualified variant in SOT-23-5 on tape-and-reel. Sourced per RFQ against your line-item quantity.
