Typical application circuit
Typical Application Circuit
It is strongly recommended that an external ceramic bypass
capacitor, CBYP, in the range of 0.01 F to 0.1 F be connected
between the VCC pin and the supply and GND pin to reduce
both external noise and noise generated by the chopper-stabiliza-
tion technique. (The diagram at the right shows CBYP at 0.1 F.)
CBYP should be installed so that the traces that connect it to the
A3250/A3251 are no greater than 5 mm in length.
The series resistor RS, in combination with CBYP creates a filter
for EMI pulses. (Additional information on EMC is provided
on the Allegro MicroSystems Web site.) RS will have a drop
of approximately 800 mV. This must be taken into consider-
ation when determining the minimum VCC requirement for the
A3250/A3251. The pull-up resistor, RL, should be chosen to
limit the current through the output transistor; do not exceed the
maximum continuous output current of the device.
