Sensitive Two-Wire Chopper-Stabilized Unipolar Hall Effect Switches  
Application Information  
For additional general application information, visit the Allegro  
MicroSystems Web site at www. allegromicro.com.  
Typical Application Circuit  
The A114x family of devices must be protected by an external  
V+  
bypass capacitor, CBYP, connected between the supply, VCC,  
and the ground, GND, of the device. CBYP reduces both external  
VCC  
B
noise and the noise generated by the chopper-stabilization func-  
tion. As shown in figure 3, a 0.01 µF capacitor is typical.  
A114x  
CBYP  
Installation of CBYP must ensure that the traces that connect it to  
the A114x pins are no greater than 5 mm in length.  
0.01 uF  
GND  
GND  
B
All high-frequency interferences conducted along the supply  
lines are passed directly to the load through CBYP, and it serves  
only to protect the A114x internal circuitry. As a result, the load  
ECU (electronic control unit) must have sufficient protection,  
other than CBYP, installed in parallel with the A114x.  
A

B
Package UA Only  
Maximum separation 5 mm  
RSENSE  
A series resistor on the supply side, RS (not shown), in combi-  
nation with CBYP, creates a filter for EMI pulses. (Additional  
information on EMC is provided on the Allegro MicroSystems  
Web site.)  
ECU  
Figure 3. Typical application circuit  
When determining the minimum VCC requirement of the A114x  
device, the voltage drops across RS and the ECU sense resistor,  
RSENSE, must be taken into consideration. The typical value for  
RSENSE is approximately 100 Ω.
