LTC4444EMS8E#TRPBF

Analog Devices · Pre-ordered Chips · MSOP-8-EP

LTC4444EMS8E#TRPBF from Analog Devices, in a MSOP-8-EP. 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 TINP input High side input signal referenced to GND that controls the high side driver output TG, with thresholds VIH 2.75V and VIL 2.3V typical.
2 BINP input Low side input signal that controls the low side driver output BG, with thresholds VIH 2.75V and VIL 2.3V typical.
3 VCC power_in Supply pin (7.2V to 13.5V operating) powering input buffers, logic and the BG driver, and TG through an external diode to BOOST; needs a low ESR ceramic bypass capacitor to GND.
4 BG output Low side gate driver output (bottom gate) swinging between VCC and GND, with 3A typical peak pull-up current.
5 NC unconnected No connect; no connection required.
6 BOOST power_in High side bootstrapped supply (up to 114V), with an external capacitor to TS and normally a bootstrap diode from VCC.
7 TG output High side gate driver output (top gate) swinging between TS and BOOST, with 2.5A typical peak pull-up current.
8 TS passive High side MOSFET source connection (top source, switching node), rated -5V to 100V.
9 GND power_in Exposed pad ground; must be soldered to PCB ground for optimal thermal performance (about 40°C/W).
