Dual-inverting, dual-noninvertering, and complementary outputs are standard logic options offered. The MCP14E3/MCP14E4/MCP14E5 drivers are capable of operating from a 4.5V to 18V single power supply and can easily charge and discharge 2200 pF gate capacitance in under 15 ns (typical). They provide low impedance in both the ON and OFF states to ensure the MOSFET’s intended state will not be affected, even by large transients. The MCP14E3/ MCP14E4/MCP14E5 inputs may be driven directly from either TTL or CMOS (2.4V to 18V). Additional control of the MCP14E3/MCP14E4/ MCP14E5 outputs is allowed by the use of separate enable functions. The ENB_A and ENB_B pins are active high and are internally pulled up to VDD. The pins maybe left floating for standard operation. The MCP14E3/MCP14E4/MCP14E5 dual-output 4.0A driver family is offered in both surface-mount and pinthrough-hole packages with a -40°C to +125°C temperature rating. The low thermal resistance of the thermally enhanced DFN package allows for greater power dissipation capability for driving heavier capacitive or resistive loads. These devices are highly latch-up resistant under any conditions within their power and voltage ratings. They are not subject to damage when up to 5V of noise spiking (of either polarity) occurs on the ground pin. They can accept, without damage or logic upset, up to 1.5A of reverse current being forced back into their outputs. All terminals are fully protect against Electrostatic Discharge (ESD) up to 4 kV.

TABLE 3-1: 8-Pin PDIP, SOIC 1 2 3 4 5 6 7 8 — Note: Duplicate pins must be connected for proper operation. 3.1 Control Inputs A and B 3.5 Enable A (ENB_A) The MOSFET driver inputs are a high-impedance TTL/ CMOS compatible input. The inputs also have hysteresis between the high and low input levels, allowing them to be driven from slow rising and falling signals and to provide noise immunity. 3.2 Outputs A and B The ENB_A pin is the enable control for Output A. This enable pin is internally pulled up to VDD for active high operation and can be left floating for standard operation. When the ENB_A pin is pulled below the enable pin Low Level Input Voltage (VEN_L), Output A will be in the off state regardless of the input pin state. Outputs A and B are CMOS push-pull outputs that are capable of sourcing and sinking 4.0A of peak current (VDD = 18V). The low output impedance ensures the gate of the MOSFET will stay in the intended state even during large transients. These outputs also have a reverse latch-up rating of 1.5A. 3.6 Enable B (ENB_B) 3.3 Supply Input (VDD) The ENB_B pin is the enable control for Output B. This enable pin is internally pulled up to VDD for active high operation and can be left floating for standard operation. When the ENB_B pin is pulled below the enable pin Low-Level Input Voltage (VEN_L), Output B will be in the off state regardless of the input pin state. VDD 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 ceramic capacitor. This bypass capacitor provides a localized low-impedance path for the peak currents that are to be provided to the load. 3.7 DFN Exposed Pad The exposed metal pad of the DFN package is not internally connected to any potential. Therefore, this pad can be connected to a ground plane or other copper plane on a printed circuit board to aid in heat removal from the package. 3.4 Ground (GND) Ground is the device return pin. The ground pin(s) should have a low impedance connection to the bias supply source return. High peak currents will flow out the ground pin(s) when the capacitive load is being discharged. © 2008 Microchip Technology Inc.

In high frequency switching power supplies, the PWM controller may not have the drive capability to directly drive the power MOSFET. A MOSFET driver like the MCP14E3/MCP14E4/MCP14E5 family can be used to provide additional source/sink current capability. An additional degree of control has been added to the MCP14E3/MCP14E4/MCP14E5 family. There are separate enable functions for each driver that allow for the immediate termination of the output pulse regardless of the state of the input signal. Input Output CL = 2200 pF Input MCP14E4 (1/2 MCP14E5) +5V Input 0V 18V Output 0V 10% 10% tD1 90% 90% 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 (tR), fall time (tF), and propagation delays (tD1 and tD2). The MCP14E3/MCP14E4/ MCP14E5 family of drivers can typically charge and discharge a 2200 pF load capacitance in 15 ns along with a typical matched propagation delay of 50 ns. Figure 4-1 and Figure 4-2 show the test circuit and timing waveform used to verify the MCP14E3/ MCP14E4/MCP14E5 timing. VDD = 18V 1 µF 0.1 µF Ceramic tR tD2 90% tF 10% FIGURE 4-2: Waveform. Non-Inverting Driver Timing 4.3 Enable Function The ENB_A and ENB_B enable pins allow for independent control of OUT A and OUT B respectively. They are active high and are internally pulled up to VDD so that the default state is to enable the driver. These pins can be left floating for normal operation. When an enable pin voltage is above the enable pin high threshold voltage, VEN_H (2.4V typical), that driver output is enabled and allowed to react to changes in the INPUT pin voltage state. Likewise, when the enable pin voltage falls below the enable pin low threshold voltage, VEN_L (2.0V typical), that driver output is disabled and does not respond the changes in the INPUT pin voltage state. When the driver is disabled, the output goes to a low state. Refer to Table 4-1 for enable pin logic. The threshold voltages of the enable function are compatible with logic levels. Hysteresis is provided to help increase the noise immunity of the enable function, avoiding false triggers of the enable signal during driver switching. For robust designs, it is recommended that the slew rate of the enable pin signal be greater than 1 V/ns. There are propagation delays associated with the driver receiving an enable signal and the output reacting. These propagation delays, tD3 and tD4, are graphically represented in Figure 4-3.

Large currents are required to charge and discharge capacitive loads quickly. For example, 2.5A are needed to charge a 2200 pF load with 18V in 16 ns. To operate the MOSFET driver over a wide frequency range with low supply impedance, a ceramic and low ESR film capacitor are recommended to be placed in parallel between the driver VDD and GND. A 1.0 µF low ESR film capacitor and a 0.1 µF ceramic capacitor 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. 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 and discharging cycle of a MOSFET is: EQUATION 4-2: P L = f × C T × V DD Where: f CT VDD = = = 2 Switching frequency Total load capacitance MOSFET driver supply voltage 4.5 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. © 2008 Microchip Technology Inc.

Refer to the DC Characteristic table for the quiescent current draw for specific combinations of input and enable pin states. The quiescent power dissipation is: EQUATION 4-3: P Q = ( I QH × D + I QL × ( 1 – D ) ) × V DD Where: IQH D IQL VDD = = = = Quiescent current in the high state Duty cycle Quiescent current in the low state MOSFET driver supply voltage 4.6.3 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 describes as: EQUATION 4-4: P CC = CC × f × V DD Where: CC f VDD = = = Cross-conduction constant (A*sec) Switching frequency MOSFET driver supply voltage DS22062B-page 14 © 2008 Microchip Technology Inc. MCP14E3/MCP14E4/MCP14E5 5.0 5.1 PACKAGING INFORMATION Package Marking Information (Not to Scale) 8-Lead DFN-S (6x5) Example: XXXXXXX XXXXXXX XXYYWW NNN MCP14E3 e3 E/MF^^ 0814 256 8-Lead PDIP (300 mil) XXXXXXXX XXXXXNNN YYWW Example: MCP14E3 e3 E/P^^256 0814 8-Lead SOIC (150 mil) XXXXXXXX XXXXYYWW NNN Example: MCP14E3E SN^^0814 e3 256 Legend: XX...X Y YY WW NNN e3 * Note: Customer-specific information Year code (last digit of calendar year) Year code (last 2 digits of calendar year) Week code (week of January 1 is week ‘01’) Alphanumeric traceability code Pb-free JEDEC designator for Matte Tin (Sn) This package is Pb-free.
