NSi6602B-DSWR

NOVOSENSE · Isolators - Gate Drivers · SOIC-16-300mil

NSi6602B-DSWR from NOVOSENSE, in a SOIC-16-300mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 INA input TTL/CMOS-compatible input signal for channel A. Internal pull-down to GNDI; tie to GNDI if unused.
2 INB input TTL/CMOS-compatible input signal for channel B. Internal pull-down to GNDI; tie to GNDI if unused.
3 VDDI power_in Input-side supply (2.7-5.5V recommended, 6V absolute max). Place a bypass capacitor from VDDI to GNDI close to the pin. Pins 3 and 8 are internally tied.
4 GNDI power_in Input-side ground reference for VDDI and the logic input pins.
5 DISABLE input Active-high disable for both isolator inputs and driver outputs. Enables normal operation when asserted low or left open; tie to GNDI if unused.
6 DT input Programmable deadtime. Tie to VDDI to allow outputs to overlap, or place a 1kΩ-200kΩ resistor R_DT between DT and GNDI so t_DT (ns) = 10 × R_DT (kΩ). Recommended to parallel a low-ESR ≥2.2nF capacitor.
7 NC unconnected No internal connection.
8 VDDI power_in Input-side supply (2.7-5.5V). Internally tied to pin 3; bypass to GNDI close to the pin.
9 GNDB power_in Ground reference for output channel B (VDDB / OUTB return).
10 OUTB output Gate driver output for channel B. 4A peak source / 6A peak sink, referenced to GNDB and powered from VDDB.
11 VDDB power_in Driver-side supply for channel B (7-25V recommended, 30V absolute max). Bypass to GNDB.
12 NC unconnected No internal connection. Part of the isolation gap between channels A and B.
13 NC unconnected No internal connection. Part of the isolation gap between channels A and B.
14 GNDA power_in Ground reference for output channel A (VDDA / OUTA return).
15 OUTA output Gate driver output for channel A. 4A peak source / 6A peak sink, referenced to GNDA and powered from VDDA.
16 VDDA power_in Driver-side supply for channel A (7-25V recommended, 30V absolute max). Bypass to GNDA.
