General Description

The MCP1401/02 are high speed MOSFET drivers

capable of providing 500 mA of peak current. The

inverting or non-inverting single channel output is

directly controlled from either TTL or CMOS (3V to

18V). These devices also feature low shoot-through

current, matched rise/fall times and propagation delays

which make them ideal for high switching frequency

applications.

The MCP1401/02 devices operate from a 4.5V to 18V

single power supply and can easily charge and

discharge 470 pF gate capacitance in under 19 ns

(typical). They provide low enough impedances in both

the on and off states to ensure the MOSFETs intended

state will not be affected, even by large transients.

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

500 mA of reverse current being forced back into their

outputs. All terminals are fully protect against

Electrostatic Discharge (ESD) up to 3 kV (HBM) and

400V (MM).

MCP1401/02 4.0 APPLICATION INFORMATION 4.1 General Information VDD = 18V 1 µF 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 MOSFET driver like the MCP1401/02 family can be used to provide additional source/sink current capability. 4.

MCP1401/02 4.5 Power Dissipation 4.5.2 The total internal power dissipation in a MOSFET driver is the summation of three separate power dissipation elements. EQUATION 4-1: P T = P L + P Q + P CC Where: PT = Total power dissipation PL = Load power dissipation PQ = Quiescent power dissipation PCC = Operating power dissipation 4.5.1 The power dissipation associated with the quiescent current draw depends upon the state of the input pin.
