L6390 High-voltage high and low side driver - 1

August 2010 Doc ID 14493 Rev 5 1/22 22 L6390 High-voltage high and low side driver Features ¡ High voltage rail up to 600 V ¡ dV/dt immunity ± 50 V/nsec in full temperature range ¡ Driver current capability: – 290 mA source, – 430 mA sink ¡ Switching times 75/35 nsec rise/fall with 1 nF load ¡ 3.3 V, 5 V TTL/CMOS inputs with hysteresis ¡ Integrated bootstrap diode ¡ Operational amplifier for advanced current sensing ¡ Comparator for fault protections ¡ Smart shut down function ¡ Adjustable dead-time ¡ Interlocking function ¡ Compact and simplified layout ¡ Bill of material reduction ¡ Effective fault protection ¡ Flexible, easy and fast design Applications ¡ Motor driver for home appliances, factory automation, industrial drives. ¡ HID ballasts, power supply units. Description The L6390 is a high-voltage device manufactured with the BCD “OFF-LINE” technology. It is a single chip half-bridge gate driver for N-channel power MOSFET or IGBT. The high side (floating) section is designed to stand a voltage rail up to 600 V. The logic inputs are CMOS/TTL compatible down to 3.3 V for easy interfacing microcontroller/DSP. The IC embeds an operational amplifier suitable for advanced current sensing in applications such as field oriented motor control. An integrated comparator is available for protections against overcurrent, overtemperature, etc. SO-16 DIP-16 Table 1.

Pin connection L6390 4/22 Doc ID 14493 Rev 5 2 Pin connection Figure 2. Pin connection (top view) Table 2. Pin description Pin n # Pin name Type Function 1 LIN I Low side driver logic input (active low) 2 SD/OD (1) 1. The circuit provides less than 1 V on the LVG and HVG pins (@ Isink = 10 mA), with VCC > 3 V. This allows omitting the “bleeder” resistor connected between the gate and the source of the external MOSFET normally used to hold the pin low; the gate driver assures low impedance also in SD condition.
