DESCRIPTION
The MAS9171A is an eight channel protection
circuit for microprocessors in automotive
applications. All inputs are protected against energy
rich pulses according to DIN40839/ISO7637.
Internal analog filters and suitable input threshold
FEATURES
• 8 digital channels
• Supply voltage 3.3 V/5 V
• Low supply current
• High voltage inputs
• Internal analog filter
• -40°C to +125°C
• SO-18 package
BLOCK DIAGRAM
voltages provide the functionality within a noise
spectrum of 150 kHz up to 1 GHz without need of
external filter components. The MAS9171A is
optimized for low current consumption.
APPLICATION
• Replacement of protection circuitry in car
electronics and industrial bus systems
