Functional Description
transistors as well as to protect them against
undesirable gate overvoltages.
Figure 17
Gate Driver
At voltages below the undervoltage lockout threshold
V
VCCoff the gate drive is active low.
The driver-stage is optimized to minimize EMI and to
provide high circuit efficiency. This is done by reducing
the switch on slope when reaching the external Power
Switch threshold. This is achieved by a slope control of
the rising edge at the driver’s output (see Figure 18).
Figure 18
Gate Rising Slope
Thus the leading switch on spike is minimized. When
the external Power Switch is switched off, the falling
shape of the driver is slowed down when reaching 2V
to prevent an overshoot below ground. Furthermore the
driver circuit is designed to eliminate cross conduction
of the output stage.
3.8
Protection Unit (Auto Restart Mode)
An overload, open loop and overvoltage detection is
integrated within the Protection Unit. These three
failure modes are latched by an Error-Latch. Additional
thermal shutdown is latched by the Error-Latch. In case
of those failure modes the Error-Latch is set after a
blanking time of 5µs and the external Power Switch is
shut down. That blanking prevents the Error-Latch from
distortions caused by spikes during operation mode.

Overload & Open loop with normal
load
Figure 19
Auto Restart Mode
Figure 19 shows the Auto Restart Mode in case of
overload or open loop with normal load. The detection
of open loop or overload is provided by the Comparator
C3, C4 and the AND-gate G2 (see Figure20).
