MIC4423/4424/4425 Micrel, Inc. MIC4423/4424/4425 Dual 3A-Peak Low-Side MOSFET Driver Bipolar/CMOS/DMOS Process General Description Features The MIC4423/4424/4425 family are highly reliable BiCMOS/ Reliable, low-power bipolar/CMOS/DMOS construction DMOS buffer/driver/MOSFET drivers. They are higher out- Latch-up protected to >500mA reverse current put current versions of the MIC4426/4427/4428, which are Logic input withstands swing to 5V improved versions of the MIC426/427/428. All three families High 3A-peak output current are pin-compatible. The MIC4423/4424/4425 drivers are ca- Wide 4.5V to 18V operating range pable of giving reliable service in more demanding electrical Drives 1800pF capacitance in 25ns environments than their predecessors. They will not latch Short <40ns typical delay time under any conditions within their power and voltage ratings. Delay times consistent with in supply voltage change They can survive up to 5V of noise spiking, of either polarity, Matched rise and fall times on the ground pin. They can accept, without either damage TTL logic input independent of supply voltage or logic upset, up to half an amp of reverse current (either Low equivalent 6pF input capacitance polarity) forced back into their outputs. Low supply current 3.5mA with logic-1 input The MIC4423/4424/4425 series drivers are easier to use, more 350A with logic-0 input exible in operation, and more forgiving than other CMOS Low 3.5 typical output impedance or bipolar drivers currently available. Their BiCMOS/DMOS Output voltage swings within 25mV of ground or V . S construction dissipates minimum power and provides rail-to- 426/7/8-, 1426/7/8-, 4426/7/8-compatible pinout rail voltage swings. Inverting, noninverting, and differential congurations Primarily intended for driving power MOSFETs, the MIC4423/4424/4425 drivers are suitable for driving other loads (capacitive, resistive, or inductive) which require low-imped- ance, high peak currents, and fast switching times. Heavily loaded clock lines, coaxial cables, or piezoelectric transducers are some examples. The only known limitation on loading is that total power dissipated in the driver must be kept within the maximum power dissipation limits of the package. Note: See MIC4123/4124/4125 for high power and narrow pulse applications.
