MIC4120/4129 Micrel, Inc. MIC4120/4129 6A-Peak Low-Side MoSfet Driver Bipolar/CMoS/DMoS Process General Description eaturesf CMOS Construction MIC4120 and MIC4129 MOSFET drivers are resilient, Latch-Up Protected: Will Withstand >200mA efficient, and easy to use. The MIC4129 is an inverting Reverse Output Current driver, while the MIC4120 is a non-inverting driver. The Logic Input Withstands Negative Swing of Up to 5V MIC4120 and MIC4129 are improved versions of the Matched Rise and Fall Times ................................25ns MIC4420 and MIC4429. High Peak Output Current ............................... 6A Peak The drivers are capable of 6A (peak) output and can drive Wide Operating Range ...............................4.5V to 20V the largest MOSFETs with an improved safe operating High Capacitive Load Drive ............................10,000pF margin. The MIC4120/4129 accept any logic input from Low Delay Time .............................................. 55ns Typ 2.4V to V without external speed-up capacitors or resis- Logic High Input for Any Voltage From 2.4V to V S S tor networks. Proprietary circuits allow the input to swing Low Equivalent Input Capacitance (typ) ..................6pF negative by as much as 5V without damaging the part. Ad- Low Supply Current ...............450A With Logic 1 Input ditional circuits protect against damage from electrostatic Low Output Impedance ......................................... 2.5 discharge. Output Voltage Swing Within 25mV of Ground or V S Exposed backside pad packaging reduces heat MIC4120/4129 drivers can replace three or more discrete - ePAD SOIC-8L ( = 58C/W) JA components, reducing PCB area requirements, simplifying - 3mm x 3mm MLF-8L ( = 60C/W) JA product design, and reducing assembly cost. Modern BiCMOS/DMOS construction guarantees freedom Applications from latch-up. The rail-to-rail swing capability insures ad- Switch Mode Power Supplies equate gate voltage to the MOSFET during power up/down Motor Controls sequencing.
