Small SOP4-pin type with
short circuit protecting GU SOP 1 Form A
(Latch type)
Short Circuit Protection (AQY210KS)
FEATURES
1. Short circuit protection (Latch type)
When the output current exceeds a fixed
amount, it is cut and the off state is
maintained. The device can be restored
by turning off the input current and then
turning it back on.
2. Miniature SOP4-pin package
3. Controls low-level analog signals
4. Low-level off state leakage current
TYPICAL APPLICATIONS
• Modem and telephone equipment
• Measuring and testing equipment
• Security equipment
• Industrial equipment
RoHS compliant
