Sin/Cos INTERPOLATION IC WITH RS422 DRIVER
REVERSE POLARITY PROTECTION
Rev F3, Page 32/43
iC-MQ is protected against a reversal of the supply
voltage and has short-circuit-proof, error-tolerant line
drivers. A defective device cable or one wrongly con-
nected is tolerated by iC-MQ. All circuitry components
which draw the monitored supply voltage from VDDS
and GNDS are also protected.
The following pins are also reverse polarity protected:
PA, NA, PB, NB, PZ, NZ, ERR, VDD, GND and ACO.
Conditions: This is based on the condition that GNDS
only receives load currents from VDDS. The maximum
voltage difference between GNDS and another pin
should not exceed 6 V, the exception here being pin
ERR (see Test Mode page 33).
