MIC4416/7 IttyBitty Low-Side MOSFET Driver Features General Description +4.5V to +18V Operation The MIC4416 and MIC4417 IttyBitty low-side MOSFET drivers are designed to switch an N-channel Low Steady-State Supply Current enhancement-type MOSFET from a TTL-compatible -50 A Typical, Control Input Low control signal in low-side switch applications. The - 370 A Typical, Control Input High MIC4416 is non-inverting and the MIC4417 is inverting. 1.2A Nominal Peak Output These drivers feature short delays and high peak -3.5 Typical Output Resistance at 18V current to produce precise edges and rapid rise and fall Supply times. Their tiny 4-lead SOT-143 package uses minimal space. -7.8 Typical Output Resistance at 5V Supply 25 mV Maximum Output Offset from Supply or The MIC4416/7 are powered from a +4.5V to +18 Ground supply voltage. The on-state drive output voltage is approximately equal to the supply voltage (no internal Operates in Low-Side Switch Circuits regulators or clamps). High supply voltages, such as TTL-Compatible Input Withstands 20V 10V, are appropriate for use with standard N-channel ESD Protection MOSFETs. Low supply voltages, such as 5V, are Inverting and Non-Inverting Versions appropriate for use with logic-level N-channel MOSFETs. Applications In a low-side configuration, the drive can control a MOSFET that switches any voltage up to the rating of Battery Conservation the MOSFET. The MIC4416/7 are available in the Solenoid and Motion Control SOT-143 package and are rated for the 40C to Lamp Control +85C ambient temperature range.
