19 DIAG
Diagnostic output. This open drain output reports the IC working condition.
The bad condition (as undervoltage, overcurrent, overtemperature) turns
the output low.
5V
C
Pump oscillator voltage. At this pin is available the built-in circuitry to supply
the switch driver at about 10 V higher than V
S
. To use this feature, connect a
capacitor across pin 4 and pin 5. The suggested value assures a fast
transition and a minimum output drop voltage even in worse condition.
Using the four channels contemporarily, values less than 6.8 nF have to be
avoided.
4V
P
Bootstrapped voltage. At this pin is available the 11 V oscillation for the
charge pump, at a typical frequency of 200 kHz.
