INA

INB

Input signal channel A

Logic input with TTL compatible thresholds and internal pull-down resistor

Input signal channel B

Logic input with TTL compatible thresholds and internal pull-down resistor

3,8

VDDI

Input-side supply voltage (operating range: 3 V to 17 V)

GNDI

Ground primary-side

DIS/ EN

Disable input channel A and B (active high)

If DIS is low or lef open, OUTA/OUTB are controlled by INA/INB

DIS high causes OUTA/OUTB low

ENABLE input channel A and B (active high)

If EN is high, OUTA/OUTB are controlled by INA/INB

EN low or lef open causes OUTA/OUTB low

STP/DTC Shoot-through Protection (STP) and Dead-Time Control (DTC)

If STP/DTC is high or lef open, OUTA and OUTB can overlap (SPT and DTC

disabled).

If STP/DTC is connected to GNDI with a resistance R_DTC, OUTA and OUTB

cannot overlap and a “safe dead-time” can be configured: t_dt[ns] = 10

x R_DTC[kΩ]

If STP/DTC is connected to GNDI, OUTA and OUTB cannot overlap (STP only

enabled)

Connecting capacitors to the DTC pin must be avoided.

N.C.

No internal connection

GNDB

OUTB

Ground secondary-side channel B

Output secondary-side channel B

Low-impedance output with source and sink capability

VDDB

Supply secondary-side channel B (operating range: UVLO to 20 V)
