Ë
2 × 4 bidirectional input/output stages at 24 V
Input/output mode programmable in 4-bit blocks
Guaranteed high-side driving capability of 100 mA
dc
and
500 mA
peak
for pulse load
Short-circuit-proof drivers with high dielectric strength
Low saturation voltage of 0.6 V at 100 mA and 2 V at 500 mA
Integrated flyback circuits
PWM function with programmable duty cycle
Flash mode for the outputs
Power outputs can be disabled together
Programmable current sources define logic levels and allow
load monitoring
Digital input filters with externally adjustable filtering times
Can be bus operated due to the high-speed µP interface
Programmable interrupt output
Voltage and two-stage temperature monitoring
APPLICATIONS
Ë
