MIC4427YN

MICREL SEMICONDUCTOR  MIC4427YN  双路驱动器芯片, MOSFET, 低压侧, 4.5V-18V电源, 1.5A输出, 23ns延迟, DIP-8

The is a highly-reliable dual non-inverting low-side MOSFET Driver fabricated on a BiCMOS/DMOS process for low power consumption and high efficiency. This driver translates TTL or CMOS input logic levels to output voltage levels that swing within 25mV of the positive supply or ground. Comparable bipolar devices are capable of swinging only to within 1V of the supply. The MIC4427 is pin-compatible replacements for the MIC426 with improved electrical performance and rugged design. It can withstand up to 500mA of reverse current without latching and up to 5V noise spikes on ground pins. Primarily intended for driving power MOSFETs, MIC4426 driver is suitable for driving other loads which require low-impedance, high peak current and fast switching time. Other applications include driving heavily loaded clock lines, coaxial cables or piezoelectric transducers.
