BUS IC DC/DC CONVERTER MOTOR DRIVER IC RIPPLE COUNTER DRIVER IC I/O IC SENSOR IC SENSOR INTERFACE IC HALIOS® optical switch HALIOS® Micromouse ÿ Hall sensor interface 8 *, par. out Hall sensor interface 6 *, ser. out PIR controller Hall sensor interface 4 *, par. out ÿ Hall sensor- and contact monitor (8 channel, parallel interface) FEATURES DESCRIPTION PINNING ÿ Supply voltage range VS 5.25 to 25V The IC is developed for automotive applications. It continuously ÿ Supply voltage range VDD 4.75 to 5.25V monitors up to 8 hall sensors or switches to GND. ÿ Maximum overvoltage protection up to 40V ÿ Low standby current (typical IS = 13µA) The input currents are compared to internal references. Currents ÿ Contact status monitoring by comparison of the exceeding – 11mA will force a logic ‘0’ at the output, while currents switch resistance with internal reference higher than -6mA will result in a logic ‘1’ at the output. ÿ Inputs are current limited ÿ High noise immunity If the IC is used to monitor switches, the switch resistance must ÿ Overtemperatur protected be higher than 5kÝ for ‘1’ and less than 330Ý for ‘0’ at the out- ÿ – 40°C to + 125 ºC operating temperature put. ÿ SO20w package The input current as well as the tristate driver are activated with APPLICATION the enable pin. Due to the tristate outputs the IC can be used in ÿ Automotive electronics ÿ Monitor for Hall Sensors ÿ Monitor for mechanical switches BLOCK DIAGRAM E910.41 bus configuration.
