NORWOOD, Mass.--(EON: Enhanced Online News)-- Analog Devices, Inc. (ADI), announces a family of new high-speed 18-volt MOSFET drivers that provide 2-A (amps) and 4-A peak currents. Among the industry?s fastest, they feature propagation delays of 14 ns to 35 ns (nanoseconds) and edge rise/fall times of 10 ns to 25 ns.

The ADP36xx MOSFET driver family improves system reliability with the inclusion of over-temperature protection, UVLO (under-voltage lockout) and precision shutdown capability. The drivers can be used to complement PWM (pulse width modulation) controllers, such as ADI?s award-winning ADP1043A digital controller, improving system efficiency, while enabling high switching frequencies in isolated power conversion and motor control systems.

These new high-current, high-speed, dual 18-volt drivers are capable of driving two independent N-channel power MOSFETs. Using industry-standard packages, the parts have an internal temperature sensor and provide two levels of over-temperature protection: warning and shutdown at extreme junction temperatures. The shutdown function, generated from a precise internal comparator, provides fast system enable or shutdown, allowing redundant over-voltage protection and complementing the protection function of the switching controller.

A wide input voltage range allows the drivers to be compatible with both analog and digital PWM controllers. Digital power controllers are powered by a low voltage supply, while the drivers are powered by a higher voltage supply. UVLO and hysteresis functions allow safe startup and shutdown of the higher voltage supply when used with low-voltage digital controllers. The device families are available in thermally enhanced SOIC_EP (small outline package with exposed pad) and Mini SO_EP (mini small outline package with exposed pad) packaging to maximize high frequency drive capability in a small PCB (printed circuit board) area.
