Timer capacitor; the capacitor defines the time for the channel 1 shut down, after overload of
the external MOS transistor has been detected.
Supply voltage.
Timer capacitor; the capacitor defines the time for the channel 2 shut down, after overload of
the external MOS transistor has been detected.
Programming resistor for overload detetcion threshold; the resistor from this pin to ground
defines the drain pin current and the charging of the timer capacitor.
Input 3; equal to IN1.
Input 2; equal to IN1.
Input 1; logic signal applied to this pin controls the driver 1; this pin features a current source
to assure defined high status when the pin is open.
Enable logic signal high on this pin enables all channels
Ground
Gate 3 driver output; current source from CP or ground
Gate 2 driver output; current source from CP or ground
Source 2 sense input; monitors the source voltage.
Source 1 sense input; monitors the source voltage.
Gate 1 driver output; current source from CP or ground
Drain 2 sense input; a programmable input bias current defines the drop across the external
resistor R
Drain 1 sense input; a programmable input bias current defines the drop across the external
resistor R
Charge pump capacitor; a alternating current source at this pin charges the connected
capacitor C
to charge all the three gates of the power MOS transistors.
