MIC4126/27/28 Dual 1.5A-Peak Low-Side MOSFET Drivers in Advanced Packaging Features General Description Dual 1.5A-Peak Drivers The MIC4126, MIC4127, and MIC4128 family are highly-reliable dual 1.5A low-side MOSFET drivers 4.5V to 20V Operating Range fabricated on Microchips BiCMOS/DMOS process. Exposed Backside Pad Packaging Reduces Heat The devices feature low power consumption and high - ePAD SOIC-8L ( = 58C/W) JA efficiency. The MIC4126/27/28 translate TTL or CMOS - ePAD MSOP-8L ( = 60C/W) JA input logic levels to output voltage levels that swing - VDFN ML-8L ( = 60C/W) within 25mV of the positive supply or ground whereas JA comparable bipolar devices are capable of swinging Bipolar/CMOS/DMOS Construction only to within 1V of the supply. The MIC4126/7/8 is - 25mV maximum output offset from supply or available in three configurations: dual inverting, dual ground noninverting, and complimentary output. Latch-Up Protection to >200mA Reverse Current The MIC4126/27/28 offer pin-compatible as well as Switches 1000pF in 25ns smaller footprint replacements for the MIC4426/27/28 Logic-Input Threshold Independent of Supply with improved packaging and electrical performance. Voltage The MIC4126/27/28 are available in exposed pad, Logic-Input Protection to 5V EPAD, SOIC-8L and MSOP-8L options as well as a 6pF Typical Equivalent Input Capacitance small-size VDFN ML-8L option. The devices have an Dual Inverting, Dual Noninverting, and input operating range of 4.5V to 20V. Complementary Configurations Primarily intended for driving power MOSFETs, - -40C to +125C operating junction tempera- MIC4426/7/8 drivers are suitable for driving other loads ture range (capacitive, resistive, or inductive) which require low-impedance, high peak current, and fast switching time. The devices can withstand up to 500mA of reverse current (either polarity) without latching and up to 5V noise spikes (either polarity) on ground pins.
