Mingjiada Supply ADI LTC4440 And LTC4441 Series N-Channel MOSFET Gate Drivers

In industrial power supplies, motor drives and DC-DC power conversion designs, high-performance MOSFET gate drivers directly determine the switching speed of power devices, system efficiency and overall reliability. Shenzhen Mingjiada Electronics Co., Ltd. — long-term supplier of the [ADI] LTC4440 and LTC4441 series of N-channel MOSFET gate drivers. These devices are primarily designed for high-voltage, high-speed N-channel MOSFET driving applications and are widely used in switching power supplies, motor drives, synchronous rectification, DC-DC converters, inverters, UPS systems, telecommunications power supplies and industrial automation equipment.

LTC4440 High-Side N-Channel MOSFET Gate Driver
Details: The LTC4440 is a high-frequency, high-side N-channel MOSFET gate driver designed to operate in applications with VIN up to 80V. Furthermore, the LTC4440 can safely withstand 100V VIN transients whilst continuing to operate during such transients. Its robust driving capability reduces switching losses in MOSFETs with high gate capacitance. The LTC4440’s pull-up circuit delivers a peak output current of 2.4A, whilst its pull-down circuit features an output impedance of 1.5Ω.

LTC4441 / LTC4441-1 N-Channel MOSFET Gate Drivers
Details: The LTC4441 / LTC4441-1 is an N-channel MOSFET gate driver capable of delivering a peak output current of up to 6A. The chip is designed to operate with supply voltages up to 25V and features an adjustable linear regulator for the gate drive. The gate drive voltage can be set between 5V and 8V.
The LTC4441 / LTC4441-1 features a logic-threshold driver input. This input can be driven to a potential below ground or above the driver supply voltage. The device provides a dual-function control input for disabling the driver or forcing the chip into a shutdown mode with a supply current of <12μA.

Key Features
1. Differentiated drive capability options: The LTC4440 is designed for high-side bootstrap driving, whilst the LTC4441 provides a 6A high-current push-pull drive, meeting the MOSFET drive requirements for power conversion applications ranging from small to medium and high power.
2. Comprehensive protection mechanisms: Undervoltage lockout and over-temperature protection; certain models support edge blanking to reduce false triggering caused by current sampling and minimise the risk of damage to the power loop.
3. Flexible gate voltage configuration: The LTC4441 incorporates an adjustable LDO, allowing engineers to set the gate drive voltage independently to optimise the balance between MOSFET on-resistance and switching losses.
4. Highly robust logic interfaces: TTL/CMOS-compatible inputs with hysteresis; the LTC4441 supports sub-ground level drive, ensuring stable operation in industrial environments with high levels of interference.
5. Available in multiple package options and wide-temperature versions, covering commercial, industrial and high-reliability MP-grade applications to suit different product tiers.
