PRODUCTION DATA
PIN | TYPE(1) | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
DT | 6 | I | DT
pin configurations:
|
GND | 4 | G | 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. It is recommended to use an RC filter on INA to filter high frequency noise, with R = 10 Ω to 100 Ω and C = 10 pF to 100 pF. |
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. It is recommended to use an RC filter on INB to filter high frequency noise, with R = 10 Ω to 100 Ω and C = 10 pF to 100 pF. |
NC | 7 | – | No Internal connection. |
NC | 12 | – | No internal connection. |
NC | 13 | – | No internal connection. |
OUTA | 15 | O | Output of driver A. Connect to the gate of the A channel transistor through a gate resistor. |
OUTB | 10 | O | Output of driver B. Connect to the gate of the B channel transsitor through a gate resistor. |
VCCI | 3 | P | Primary-side supply voltage. Locally decouple to GND using a low ESR/ESL capacitor located as close to the device as possible. |
VCCI | 8 | P | Primary-side supply voltage. This pin is internally shorted to pin 3. |
VDDA | 16 | P | Secondary-side power for driver A. Locally decouple 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 decouple to VSSB using low ESR/ESL capacitor located as close to the device as possible. |
VSSA | 14 | G | Ground reference for secondary side A channel. |
VSSB | 9 | G | Ground reference for secondary side B channel. |
