IXBD4410

IXBD4411

the IXBD4411 is strictly for status only.

Any gate-drive shutdown because of a

high-side fault is done locally within the

high-side IXBD4411. The IXBD4411

gate-drive will turn-off the power device

whenever an overcurrent or under

voltage condition arises. The overcurrent

sensing is active only while the gate

driver output is "high" (on). The

overcurrent fault condition is latched and

is reset on the next INH gate input

positive transition. The FLT (pin 8) of the

IXBD4411 is not used and should be

grounded.

The low-side IXBD4410 driver provides

an output pin 8 (FLT) to indicate a high-

side (IXBD4411) or a low-side

(IXBD4410) fault. This output pin is an

"open-drain" output. The IXBD4410 low-

side driver fault indications are similar to

the IXBD4411 high-side driver indications

as outlined above. A "graphic" logic

diagram of the chipset's FLT function is

presented in Fig.4. Note that this diagram

presents the logic of this function at the

"low-side" IXBD4410 driver and is not the

actual circuit. It describes the combined

logic of the "fault logic" and "hi-side fault

sense" blocks in both the IXBD4410 and

IXBD4411 as shown in Fig. 2 and 3.

The most efficient method of providing

power for the high-side driver is by

bootstrapping. This method is illustrated

in the functional drawing on page 4 and

in the application example (Fig. 6 and 9)

by diode D1 and capacitor C1. Using this

method, the power is drawn through a

high-voltage diode onto a reservoir

capacitor whenever the floating high-side

ground returns to near the real ground of

the low-side driver. When the high-side

gate is turned on and the floating ground

moves towards a higher potential, the

bootstrapping diode back-biases, and the

high-side driver draws its power solely

from the reservoir capacitor. Power may

also be provided via any isolated power

supply (usually an extra secondary on

the system housekeeping supply

switching transformer).

Both the IXBD4410 and IXBD4411

contain on-board negative charge pumps

to provide negative gate drive, which

ensures turn-off of the high- or low-side

power device in the presence of currents

induced by power device Miller capaci-

tance or from inductive ground transients.

These charge pumps provide -5 V

relative to the local driver ground when

V

DD is at +15 V, and at rated average

currents of 25 mA. The charge pump

requires two external capacitors, C7 and

C11 in Fig. 6. The charge pump

frequency is nominally 600 kHz. The

charge pump clock is turned off

whenever the difference between the V

DD

and V

EE supplies exceed 20 V, to prevent

exceeding the breakdown rating of the

IC.

Both the IXBD4410 and IXBD4411

drivers possess two local grounds each,

a common logic ground, and "Kelvin"

ground. The Kelvin ground and logic

grounds are first connected directly to

each other, and then to the Kelvin-source

of the power device for accurate over-

current measurement in the presence of

inductive transients on the power device

source terminal.

Power MOSFET or IGBT overcurrent

sensing utilizes an on-chip comparator

with a typical 300 mV threshold. In a

typical application, the current mirror pin

of the Power MOSFET or IGBT is con-

nected to a grounded, low-value resistor,

and to the overcurrent comparator input

on the high- or low-side driver. The

comparator will respond typically within

150 ns to an overcurrent condition to

shutdown the driver output. The power

switches could be protected also by

desa-turation detection (see Fig. 6, 7 and

9).

To assure maximum protection for the

phase-leg power devices, the chipset

incorporates the following Power

MOSFET and IGBT protection circuits:

Power device overcurrent or desa-

turation protection. The IXBD4410/

4411will turn off the driven device

within 150 ns of sensing an output

overcurrent or desaturation condition.

Gate-drive lockout circuitry to prevent

cross conduction (simultaneous

conduction of the low- and high-side

phase-leg power devices), either

under normal operating conditions or

when a fault occurs.

During power-up, the chipset's gate-

drive outputs will be low (off), until the

voltage reaches the under-voltage trip

point.

Under-voltage gate-drive lockout on

the low- and/or high- side driver when-

ever the respective positive power

supply falls below 9.5 V typically.

Under-voltage gate-drive lockout on

the low- and high- side driver

whenever the respective negative

power supply rises above -3 V

typically.
