ATS635LSE and
ATS636LSE
For applications it is strongly recommended that an external
ceramic bypass capacitor in the range of 0.01 μF to 0.1 μF be
connected between the supply and ground of the device to reduce
both external noise and noise generated by the chopper-stabi-
lization technique. (The diagram below shows a 0.1 μF bypass
capacitor.)
The series resistor R
creates a filter for EMC pulses. The series resistor will have a
drop of approximately 800 mV, this must be considered for the
minimum V
The small capacitor on the output of the device improves the

EMC performance of the device. The pull-up resistor should be
chosen to limit the current through the output transistor; do not
exceed the maximum continuous output current of the device.
Note: This circuit cannot be used to program the device, as the
series resistance is too large, and a minimum capacitance of
0.1 μF must be connected from VCC to GND of the SIP to pro-
vide the current necessary to blow the fuse.

effect ICs including chopper stabilization is available in
