µP INTERFACE WITH 2×4 24V HIGH-SIDE DRIVERS
Rev A1, Page 1/23
FEATURES
Ë 2 × 4 bidirectional input/output stages at 24 V
Ë Input/output mode programmable in 4-bit blocks
Ë Guaranteed high-side driving capability of 100 mAdc and
500 mApeak for pulse load
Ë Short-circuit-proof drivers with high dielectric strength
Ë Low saturation voltage of 0.6 V at 100 mA and 2 V at 500 mA
Ë Integrated flyback circuits
Ë PWM function with programmable duty cycle
Ë Flash mode for the outputs
Ë Power outputs can be disabled together
Ë Programmable current sources define logic levels and allow
load monitoring
Ë Digital input filters with externally adjustable filtering times
Ë Can be bus operated due to the high-speed µP interface
Ë Programmable interrupt output
Ë Voltage and two-stage temperature monitoring
APPLICATIONS
Ë Dual quad high-side driver as a
bidirectional µP interface with
digital filtering in industrial 24 V
