FOperation notes
(1) Thermal shutdown circuit
This circuit shuts down all the IC currents when the chip
junction temperature is increased to about 175_C (typi-
cal). The circuit is deactivated when the temperature
drops to about 155_C (typical).
(2) Hall elements connection
Hall elements can be connected in either series or paral-
lel. When connecting in series, care must be taken not to
allow the Hall output to exceed the Hall common-mode
input range.
(3) Hall input level
Switching noise may occur if the Hall input voltage
(17X22 pin) is too high. Differential inputs of about
100mV (peak to peak) are recommended.
