Table 4-1 Pin Functions
PIN TYPE (1) Description
NAME NO.
DIS 5 I Disable both driver outputs if asserted high, enable both outputs if set low. It is recommended to tie this pin to ground if not used to achieve better noise immunity. This pin is internally pulled high if left floating. It is recommended to use an RC filter on DIS pin to filter high frequency noise when connecting to a microcontroller, with R = 0 Ω to 100 Ω and C = 100 pF to 1000 pF.
DT 6 I DT pin configurations:
  • DT pin float or short to VCCI disables dead time interlock function (allows outputs to overlap)
  • Place 1.7-kΩ to 100-kΩ resistor (RDT) between DT and GND to set minimum dead time between driver outputs
  • Place 0-Ω to 150-Ω resistor, or short DT pin to GND to have two outputs interlocked
GND 4 P Primary-side ground reference. All signals in the primary side are referenced to this ground.
INA 1 I Input signal for A channel. INA input has a TTL/CMOS compatible input threshold. This pin is pulled low internally if left open. Tie this pin to ground if not used to achieve better noise immunity.
INB 2 I Input signal for B channel. INB input has a TTL/CMOS compatible input threshold. This pin is pulled low internally if left open. Tie this pin to ground if not used to achieve better noise immunity.
NC 7 — No internal connection

OUTA 15 O Output of driver A. Connect to the gate of the A channel FET or IGBT.
OUTB 10 O Output of driver B. Connect to the gate of the B channel FET or IGBT.
VCCI 3 P Primary-side supply voltage. Locally decoupled to GND using a low ESR/ESL capacitor located as close to the device as possible
VCCI 8 P This pin is internally shorted to pin 3.
VDDA 16 P Secondary-side power for driver A. Locally decoupled to VSSA using a low ESR/ESL capacitor located as close to the device as possible
VDDB 11 P Secondary-side power for driver B. Locally decoupled to VSSB using a low ESR/ESL capacitor located as close to the device as possible.
VSSA 14 P Ground for secondary-side driver A. Ground reference for secondary side A channel
VSSB 9 P Ground for secondary-side driver B. Ground reference for secondary side B channel
