? 2007 microchip technology inc. ds22052a-page 9 mcp1401/02 3.0 pin descriptions the descriptions of the pins are listed in table 3-1 . table 3-1: pin function table (1) 3.1 supply input (v dd ) v dd is the bias supply input for the mosfet driver and has a voltage range of 4.5v to 18v. this input must be decoupled to ground with a local capacitor. this bypass capacitor provides a localized low-impedance path for the peak currents that are to be provided to the load. 3.2 control input (in) the mosfet driver input is a high-impedance, ttl/ cmos-compatible input. the input also has hysteresis between the high and low input levels, allowing them to be driven from slow rising and falling signals, and to provide noise immunity. 3.3 ground (gnd) ground is the device return pin. the ground pin should have a low impedance connection to the bias supply source return. high peak currents will flow out the ground pin when the capacitive load is being discharged. 3.4 output (out) the output is a cmos push-pu ll output that is capable of sourcing and sinking 0.5a of peak current (v dd = 18v). the low output impedance ensures the gate of the external mosfet will stay in the intended state even during large transients. this output also has a reverse current latch-up rating of 0.5a. sot-23-5 symbol description 1 gnd ground 2v dd supply input 3 in control input 4 gnd ground 5 out output note 1: duplicate pins must be connected for proper operation.
mcp1401/02 ds22052a-page 10 ? 2007 microchip technology inc. 4.0 application information 4.1 general information mosfet drivers are high-speed, high current devices which are intended to source/sink high peak currents to charge/discharge the gate capacitance of external mosfets or igbts. in high frequency switching power supplies, the pwm controller may not have the drive capability to directly drive the power mosfet. a mos- fet driver like the mcp1401/02 family can be used to provide additional source/sink current capability. 4.2 mosfet driver timing the ability of a mosfet driver to transition from a fully off state to a fully on state are characterized by the drivers rise time (t r ), fall time (t f ), and propagation delays (t d1 and t d2 ). the mcp1401/02 family of drivers can typically charge and discharge a 470 pf load capacitance in 19 ns along with a typical matched propagation delay of 35 ns. figure 4-1 and figure 4-2 show the test circuit and timing waveform used to verify the mcp1401/02 timing. figure 4-1: inverting driver timing waveform. figure 4-2: non-inverting driver timing waveform. 4.3 decoupling capacitors careful layout and decoupling capacitors are highly recommended when using mosfet drivers. large currents are required to charge and discharge capacitive loads quickly. for example, approximately 550 ma are needed to charge a 470 pf load with 18v in 15 ns. to operate the mosfet driver over a wide frequency range with low supply impedance, a ceramic and low esr film capacitor is recommended to be placed in parallel between the driver v dd and gnd. a 1.0 f low esr film capacitor and a 0.1 f ceramic capacitor placed between pins 2 and 1 should be used. these capacitors should be placed close to the driver to minimized circuit board parasitics and provide a local source for the required current. 4.4 pcb layout considerations proper pcb layout is important in a high current, fast switching circuit to provide proper device operation and robustness of design. pcb trace loop area and inductance should be minimized by the use of ground planes or trace under mosfet gate drive signals, separate analog and power grounds, and local driver decoupling. placing a ground plane beneath the mcp1401/02 will help as a radiated noise shield as well as providing some heat sinking for power dissipated within the device. 0.1 f +5v 10% 90% 10% 90% 10% 90% 18v 1f 0v 0v mcp1401 c l = 470 pf input input output t d1 t f t d2 output t r v dd = 18v ceramic 90% input t d1 t f t d2 output t r 10% 10% 10% +5v 18v 0v 0v 90% 90% 0.1 f 1f mcp1402 c l = 470 pf input output v dd = 18v ceramic
? 2007 microchip technology inc. ds22052a-page 11 mcp1401/02 4.5 power dissipation the total internal power dissipation in a mosfet driver is the summation of three separate power dissipation elements. equation 4-1: 4.5.1 capacitive load dissipation the power dissipation caused by a capacitive load is a direct function of frequency, total capacitive load, and supply voltage. the power lost in the mosfet driver for a complete charging a nd discharging cycle of a mosfet is shown in equation 4-2 . equation 4-2: 4.5.2 quiescent power dissipation the power dissipation associated with the quiescent current draw depends upon the state of the input pin. the mcp1401/02 devices have a quiescent current draw when the input is high of 850 ma (typ) and 100 ma (typ) when the input is low. the quiescent power dissipation is shown in equation 4-3 . equation 4-3: 4.5.3 operating power dissipation the operating power dissipation occurs each time the mosfet driver output transitions because for a very short period of time both mosfets in the output stage are on simultaneously. this cross-conduction current leads to a power dissipation described in equation 4-4 . equation 4-4: p t p l p q p cc ++ = where: p t = total power dissipation p l = load power dissipation p q = quiescent power dissipation p cc = operating power dissipation p l fc t v dd 2 = where: f = switching frequency c t = total load capacitance v dd = mosfet driver supply voltage p q i qh di ql 1 d ?
