• _{Low EMC sensitivity and emission}
• _{Adjustable dead time with shoot through protection}
• _{Deactivation of dead time and shoot through protection possible}
• _{Short circuit protection for each Mosfet}
• _{Driver undervoltage shut down}
• _{Reverse polarity protection for the driver IC}
• _{Disable function}
• _{Input with TTL characteristics}
• _{1 bit diagnosis}
• _{Integrated bootstrap diodes}
Application
P-DSO 20
• _{Dedicated for DC-brush high current motor bridges in PWM control mode and adapted for use in injector and}
valve applications for 12, 24 and 42V powernet applications. Useable as four fold lowside driver for unipolar 4
phase motor drives.
• _{The two half bridges can operate independently. The two half bridges can even operate at different supply}
voltages.
