Undervoltage Lockout
When the supply voltage falls below the undervoltage lockout
level, V
remains in that state until the voltage level is restored to to the
V
have no effect until voltage is restored. This prevents false sig-
nals 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 range of supply voltage levels. For applications using an
unregulated power supply, transient protection must be added
externally. For applications using a regulated supply line, EMI
and RFI protection may still be required. The circuit shown in

Internal Electronics
The ATS625LSG contains a self-calibrating Hall effect IC
that possesses 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 electron-
ics are integrated on the same silicon substrate by a proprietary
BiCMOS process. Changes in temperature do not greatly affect
this device due to the stable amplifier design and the offset rejec-
tion circuitry.
