MIC4426/4427/4428 Micrel, Inc. MIC4426/4427/4428 Dual 1.5A-Peak Low-Side MOSFET Driver General Description Features The MIC4426/4427/4428 family are highly-reliable dual low- Bipolar/CMOS/DMOS construction side MOSFET drivers fabricated on a BiCMOS/DMOS process Latch-up protection to >500mA reverse current for low power consumption and high efciency. These drivers 1.5A-peak output current translate TTL or CMOS input logic levels to output voltage 4.5V to 18V operating range levels that swing within 25mV of the positive supply or ground. Low quiescent supply current Comparable bipolar devices are capable of swinging only 4mA at logic 1 input to within 1V of the supply. The MIC4426/7/8 is available in 400A at logic 0 input three congurations: dual inverting, dual noninverting, and Switches 1000pF in 25ns one inverting plus one noninverting output. Matched rise and rall times 7 output impedance The MIC4426/4427/4428 are pin-compatible replacements <40ns typical delay for the MIC426/427/428 and MIC1426/1427/1428 with im- Logic-input threshold independent of supply voltage proved electrical performance and rugged design (Refer to Logic-input protection to 5V the Device Replacement lists on the following page). They 6pF typical equivalent input capacitance can withstand up to 500mA of reverse current (either polarity) 25mV max. output offset from supply or ground without latching and up to 5V noise spikes (either polarity) Replaces MIC426/427/428 and MIC1426/1427/1428 on ground pins. Dual inverting, dual noninverting, and inverting/ Primarily intended for driving power MOSFETs, MIC4426/7/8 noninverting congurations drivers are suitable for driving other loads (capacitive, resistive, ESD protection or inductive) which require low-impedance, high peak current, and fast switching time. Other applications include driving Applications heavily loaded clock lines, coaxial cables, or piezoelectric MOSFET driver transducers. The only load limitation is that total driver power Clock line driver dissipation must not exceed the limits of the package. Coax cable driver Note See MIC4126/4127/4128 for high power and narrow Piezoelectic transducer driver pulse applications.
