ATS665LSG
Undervoltage Lockout
When the supply voltage falls below the minimum operating volt-
age, V
state of the magnetic field. This prevents false signals caused by
undervoltage conditions from propagating to the output of the IC.
Power Supply Protection
The device contains an on-chip regulator and can operate over a
wide supply voltage range. For devices that need to operate from
an unregulated power supply, transient protection must be added
externally. For applications using a regulated line, EMI/RFI
protection may still be required. The following circuit is the most
basic configuration required for proper device operation. For
CCUV
, the device turns off and stays off irrespective of the
True Zero Speed, High Accuracy, Gear Tooth Sensor IC
EMC information, contact your Allegro representative.
Internal Electronics
The ATS665 contains a self-calibrating Hall effect IC that pos-
sesses two Hall elements, a temperature compensated amplifier
and offset cancellation circuitry. The IC also contains a voltage
regulator that provides supply noise rejection over the operating
voltage range. The Hall transducers and the electronics are inte-
grated on the same silicon substrate using a proprietary BiCMOS
process. Changes in temperature do not greatly affect this device
due to the stable amplifier design and the offset rejection cir-
cuitry.
