MOSFET Drivers feature high-speed switching.
Press Release Summary:
Capable of driving 2 independent N-channel power MOSFETs, ADP36xx series delivers 2 and 4 A peak currents. High-speed switching provides propagation delays of 14-35 ns and edge rise/fall times of 10-25 ns, while over temperature protection, UVLO, and precision shutdown capabilities improve system reliability. Input voltage, up to 18 V, is compatible with analog and digital PWM controllers. Drivers can be used to complement PWM controllers while enabling high switching frequencies.

MOSFET Drivers Improve Efficiency with High Switching Speeds and Over Temperature Protection
- Analog Devices' ADP36xx family of 18-volt MOSFET drivers provides 2-A and 4-A peak currents with best-in-class propagation delays and edge rise and fall times for power conversion and control designs.
Norwood, MA (11/19/2009) - Analog Devices, Inc. (ADI), a global leader in high-performance semiconductors for signal-processing applications, today announced 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 new ADP36xx MOSFET driver family improves system reliability with the inclusion of overtemperature protection, UVLO (undervoltage 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 overtemperature 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 overvoltage 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.
