A6387DTR

Overview

The A6387DTR is a high-voltage half-bridge gate driver manufactured using BCD offline technology, designed for automotive applications. It integrates high-side and low-side drivers for N-channel Power MOSFETs or IGBTs. The high-side floating section withstands up to 550 V. Logic inputs are CMOS/TTL compatible. Key electrical parameters include a dV/dt immunity of ±50 V/nsec across the full temperature range. Driver current capabilities are 400 mA source and 650 mA sink. Switching times with a 1 nF load are 50 ns rise and 30 ns fall. Operating voltage ranges from 6.3 V to 17 V, with a junction temperature range of -40°C to 125°C.
