Half-bridge gate driver for IGBT and N-channel MOSFET stages
The STMicroelectronics L6386ED013TR is a half-bridge gate driver designed to drive IGBT and N-channel MOSFET power switches in high-voltage applications. It integrates two independent driver channels with inverting input logic, supporting bootstrap operation for the high-side gate up to 600 V. The driver delivers 400 mA source and 650 mA sink peak output current, with typical rise and fall times of 50 ns and 30 ns respectively, providing controlled switching for motor drives, power inverters, and switched-mode power supplies. The logic input thresholds of 1.5 V (VIL) and 3.6 V (VIH) allow direct interface with 3.3 V or 5 V PWM controllers and microcontrollers. Operating over a -40°C to 150°C junction temperature range, it suits industrial and automotive environments where thermal cycling is a concern.
600 V bootstrap and supply rail considerations
The 600 V maximum bootstrap voltage on the high side sets the DC bus voltage ceiling for the half-bridge. The driver supply itself is rated to 17 V maximum — a common rail for gate-drive bias. The 17 V limit means the gate drive voltage for the power switches is capped at that level, which is typical for standard IGBTs and MOSFETs.
Switching speed and gate drive strength
With 400 mA source and 650 mA sink peak current, the L6386ED013TR can drive moderate gate-charge loads without excessive switching losses. The 50 ns rise and 30 ns fall times are a practical middle ground: fast enough to keep crossover conduction short in a half-bridge, but not so aggressive that parasitic ringing becomes unmanageable without careful layout.
Temperature range and environment
Rated for junction temperature from -40°C to 150°C, this driver covers the full industrial temperature range and extends into automotive under-hood applications. The 150°C junction maximum allows operation in high-ambient enclosures or near hot power stages, but thermal design must still keep the junction below that limit.
Package and mounting
Supplied in a 14-SOIC package (0.154" body width, 3.90 mm), the L6386ED013TR is a surface-mount device that fits standard SOIC-14 footprints. The supplier device package is designated 14-SO.
Lifecycle and compliance
The L6386ED013TR is listed as Active in production status and is ROHS3 compliant. For volume or long-term program commitments, the active status means it remains a standard catalog item through STMicroelectronics distribution channels. The ROHS3 compliance covers the current regulatory requirements for lead-free assembly.
