Ultra-Sensitive Dual-Channel Quadrature Hall-Effect Bipolar Switch

Typical Applications Circuits

For applications in which the device receives its

power from unregulated sources, such as a car bat-

tery, full protection is generally required to protect the

device against supply-side transients. Speciﬁcations

for such transients vary for each application, so the

design of the protection circuit should be optimized

for each application.

This device requires minimal protection circuitry

during operation with a low-voltage regulated line.

The on-chip voltage regulator provides immunity

to power supply variations between 3.3 and 18 V.

Because the device has open-collector outputs, pull-

up resistors must be included.

If protection against coupled and injected noise is

required, then a simple low-pass ﬁlter on the supply

(RC) and a ﬁltering capacitor on each of the outputs

may also be needed, as shown in the unregulated

supply diagram.

For example, the circuit shown in the unregulated

supply diagram includes a Zener diode that offers

high voltage load-dump protection and noise ﬁltering

by means of a series resistor and capacitor. In addi-

tion, it includes a series diode that protects against

high-voltage reverse battery conditions.
