7.17 Driver
The driver circuit to the Gate of the power MOSFET has a current sourcing capability of
typically 170 mA and a current sink capability of typically 700 mA. This permits fast
turn-on and turn-off of the power MOSFET for efficient operation.
A low driver source current has been chosen to limit the
V/
t at switch-on. This reduces
Electro Magnetic Interference (EMI) and also limits the current spikes across R
sense
.

Limiting values
[1]
Equivalent to discharging a 100 pF capacitor through a 1.5 k
series resistor.
Equivalent to discharging a 200 pF capacitor through a 0.75
μ
H coil and a 10
resistor.

Table 3:
In accordance with the Absolute Maximum Rating System (IEC 60134). All voltages are measured
with respect to ground (pin 2); positive currents flow into the chip; pin V
CC
may not be current driven.
The voltage ratings are valid provided other ratings are not violated; current ratings are valid
provided the maximum power rating is not violated.
