Interface Circuit Requirements: A typical interface circuit for the BG2B is shown in Figure 4. A single control
power supply (+V S ) is connected to pin 5 of CN1 with its common at pin 6. This supply provides all of the gate
drive power for both channels via the hybrid DC to DC converters. The current drawn from the +V S supply will
vary from less than 100mA to more than 500mA depending on the switching frequency and size of IGBT being
driven. Consult the hybrid gate driver application notes for details on determining the required supply current for
the gate driver. The gate driver supply current can then be converted into current drawn from the +V S supply
using the efficiency specification on the DC to DC converter data sheet.
A 5V logic supply is connected at pin 1 of CN1 and shares the same common at pin 6 of CN1 as the
15V control supply. The 5V supply is directly connected to pin 14 of the hybrid gate driver which is internally
connected to the anode of the LED in the high speed opto coupler. The 5V supply is also used to pull the output
side of the fault isolation opto couplers high.
The control signal interface is designed for use with standard 5V CMOS logic. The control input signals at
pins 2 and 3 of connector CN1 are used to turn the IGBTs on and off. These signals are active low which means
that the gate driver output will be high (IGBT on) when they are pulled low. These control pins are connected
directly to pin 13 of the hybrid gate driver which is connected internally through a 180 Ω limiting resistor to the
cathode of the LED in the high speed opto coupler (see figure 1). When the control signal is pulled low, current
flows from the 5V logic supply through the LED to turn the gate driver’s output on. The control pins must be
pulled low with a buffer that is capable of sinking at least 16mA in order to turn on the high speed opto coupler
inside the hybrid gate driver. A CMOS buffer that actively pulls its output high in the off state (74HC04 or similar)
is recommended for maintaining good common mode noise immunity. Open collector drive that allows IN1 and
IN2 to float will degrade common mode noise immunity and is therefore not recommended.
The fault signal line on pin 4 of CN1 is active low which means that a fault condition will be indicated by
a low level signal. During normal operation pin 4 is pulled high to the +V L supply by the 4.7K resistor R3. If
either of the hybrid gate drivers detects a short circuit condition its fault isolation opto (OP1, OP2) will turn on
and pull pin 4 of CN1 low. When a fault is detected the hybrid gate drivers disable the output and produce a
fault signal for a minimum of 1ms. Any signal on the fault line that is significantly shorter than 1ms can not be a
legitimate fault so it should be ignored. Therefore, for a robust noise immune design, it is recommended that an
RC filter with a time constant of approximately 10 μ s be added between pin 4 and the controller as shown in
figure 4.
Printed Circuit Layout: Figure 5 shows the layout of the BG2B two channel gate driver board. The compact 3 ”
x 2.2 ” circuit board with only 24 components clearly demonstrates the advantage of using hybrid gate drivers
and DC to DC converters. One important feature is the use of three ground plane islands for the regions of the
PCB having high voltage differences. Two of the islands are tied to the IGBT emitter/circuit common (Pin 2 of
the DC to DC converters) of each output channel. The third island is connected to logic interface common at pin
6 of CN1. This layout provides shielding to help prevent undesirable coupling of noise between the control side
and the gate drive channels.
Additional Information: Detailed information about the operation and electrical characteristics of the M57159L-
01, VLA503-01 and VLA-504-01 hybrid gate drivers can be found on the individual device data sheets. Electrical
