L6385 high-voltage high and low side driver

Figure 16.

L6385 block diagram

The L6385 is a high-voltage device, manufactured with BCD "OFF-LINE" technology. It has

a driver structure that enables to drive independently referenced N-Channel Power

MOSFETs or IGBTs. The upper (floating) section is enabled to work with voltage rail up to

600 V. The logic inputs are CMOS/TTL compatible for easy interfacing with controlling

devices.

The main characteristic of this driver are:

●

high-voltage rail up to 600 V

●

dV/dt immunity ± 50 V/nsec in full temperature range

●

driver current capability: 400 mA source, 650 mA sink

●

switching times 50/30 nsec rise/fall

●

with 1 nF load

●

CMOS/TTL Schmitt trigger inputs with hysteresis and pull-down

●

undervoltage lockout on lower and upper driving sections

●

internal bootstrap diode

●

outputs in phase with inputs
