Product Description
Microchip HT0740LG-G is a single-channel high-voltage isolated MOSFET gate driver featuring HVCMOS technology and an 8-pin SOIC package. It is designed specifically to drive discrete MOSFETs configured as high-side switches up to 400V, providing DC isolation between input and output. Its internal supply voltage is obtained from the logic input when at high state, eliminating the need for external power supplies.
This device offers low input logic current, typically maximum 500 μA, with a minimum supply voltage of 5.5 V and maximum supply voltage of 7 V. The driver includes five outputs compatible with 5 V logic, supporting robust switching with rise times of 650 microseconds and fall times of 3 milliseconds.
The HT0740LG-G package measures 5 mm in length, 4 mm in width, and 1.65 mm in height, ideal for surface mount technology. Operating across a temperature range from -40°C to 85°C, it suits applications requiring reliability under harsh conditions.
Common uses include telecommunications systems, modems, solid-state relays, high-side switching circuits, high-end audio switch designs, avionics equipment, and automatic test machines.
±400V input to output isolation ensures device safety and signal integrity. Low input logic current reduces power consumption. No need for an external power supply simplifies system design. Compatible with standard 5V logic interfaces.
Compact SOIC surface-mount form factor. Robust operation in industrial temperature ranges. HVCMOS technology guarantees high-performance isolating drive. Browse the EnvMart electronics & electricals category for MOSFET Gate Drivers and related components.
