... N-channel, enhancement-mode, power MOSFETs used as high-side or low-side switches. The MIC5014/5 can sustain an on-state output indefinitely. The MIC5014/5 operates from a 2.75V to 30V supply. In high- side configurations, the driver can control MOSFETs that switch loads 30V. In low-side configurations, with separate supplies, the maximum switched voltage is limited only by the MOSFET ...

... Source 4 Ground 5 Gate MIC5014/5015 V+ (1) Charge Pump 15V Pin Function Supply. Must be decoupled to isolate from large transients caused by the power MOSFET drain recommended close to pins 1 and 4. Turns on power MOSFET when taken above (or below) threshold (1.0V typical). Pin 2 requires ~ switch. ...

... Note 4: Test conditions reflect worst case high-side driver performance. Low-side and bootstrapped topologies are significantly faster—see Applications Information. Maximum value of switching time seen at 125 C, unit operated at room temperature will reflect the typical value shown. Note 5: “Asserted” refers to a logic high on the MIC5014 and a logic low on the MIC5015. 1997 Operating Ratings (Notes 1,2) (Plastic DIP) ...

... The internal functions of these devices are controlled via a logic block (refer to block diagram) connected to the control input (pin 2). When the input is off (low for the MIC5014, and high for the MIC5015), all functions are turned off, and the gate of the external power MOSFET is held low via two N- channel switches. This results in a very low standby current ...

... MIC5014 (polarities should be reversed if the MIC5015 is used). One the overcurrent trip point has been reached, the comparator will go low, which shuts off the MIC5014. When the MIC5014/5015 the short is removed, feedback to the input pin insures that the MIC5014 will turn back on ...

... Also, too large of a kickback voltage (as is found in larger solenoids) can damage the MIC5014 or the power FET by forcing the Source node below ground (the MIC5014 can be driven up to 20V = +5V to +30V below ground before this happens). A catch diode has been included in this design to provide an alternate route for the inductive kickback current to flow ...

... IRF540 OSRAM Simple DC-DC Converter (Figure 11) The simplest applica- tion for the MIC5014 basic one-chip DC-DC converter. As the output (Gate) pin has a relatively high impedance, the output voltage shown will vary significantly with applied load. 12V IRF540 Guardian Electric 1725-1C-12D ...

... FET will be forward biased. This allows the reversed supply access to the load. Push-Pull Driver With No Cross-Conduction (Figure 13) As the turn-off time of the MIC5014/15 devices is much faster than the turn-on time, a simple push-pull driver with no cross conduction can be made using one MIC5014 and one MIC5015. The same control signal is applied to both inputs ...
