LTC1693-1CS8#TRPBF

Analog Devices · Gate Drive ICs · SO-8

LTC1693-1CS8#TRPBF from Analog Devices, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN1 input Driver 1 input with VCC-independent CMOS thresholds (VIL 1.1-1.7 V, VIH 2.2-3.1 V) and 1.2 V typical hysteresis for noise immunity.
2 GND1 power_in Driver 1 ground, to be connected to a low impedance ground, with the VCC1 bypass capacitor and the external MOSFET source connected directly to this pin.
3 IN2 input Driver 2 input with VCC-independent CMOS thresholds (VIL 1.1-1.7 V, VIH 2.2-3.1 V) and 1.2 V typical hysteresis for noise immunity.
4 GND2 power_in Driver 2 ground, to be connected to a low impedance ground, with the VCC2 bypass capacitor and the external MOSFET source connected directly to this pin; do not tie GND1 and GND2 together if isolation between the drivers is required.
5 OUT2 output Driver 2 noninverting output, in phase with IN2, with 1.4 A typical peak source and 1.7 A typical peak sink current capability.
6 VCC2 power_in Driver 2 power supply input, operating over 4.5 V to 13.2 V, with the driver output held off when VCC is below 4 V (UVLO).
7 OUT1 output Driver 1 noninverting output, in phase with IN1, with 1.4 A typical peak source and 1.7 A typical peak sink current capability.
8 VCC1 power_in Driver 1 power supply input, operating over 4.5 V to 13.2 V, with the driver output held off when VCC is below 4 V (UVLO).
