PIN DESCRIPTIONS

The descriptions of the pins are listed in Table 3-1.

TABLE 3-1:

PIN FUNCTION TABLE (1)

3.1

Inputs A and B

MOSFET driver inputs A and B are high-impedance,

TTL/CMOS compatible inputs. These inputs also have

300 mV of hysteresis between the high and low

thresholds that prevents output glitching even when the

rise and fall time of the input signal is very slow.

3.2

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.

3.3

Output A and B

MOSFET driver outputs A and B are low-impedance,

CMOS push-pull style outputs. The pull-down and pull-

up devices are of equal strength, making the rise and

fall times equivalent.

3.4

Supply Input (VDD)

The VDD input is the bias supply for the MOSFET driver

and is rated for 4.5V to 18V with respect to the ground

pin. The VDD input should be bypassed with local

ceramic capacitors. The value of these capacitors

should be chosen based on the capacitive load that is

being driven. A value of 1.0

μF is suggested.

3.5

Exposed Metal Pad

The exposed metal pad of the 6x5 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.
