        Description:Resistor Programmable Temperature Switches

        Key Features
        ◆  VCC: 2.5V to 5.5V
        ◆  Temperature Accuracy:
            ±2.0oC (Max.) over 0oC to 70oC
            ±3.0oC (Max.) over -40oC to 125oC
        ◆  Quiescent Current 30uA (Typ.) @ 3.3V
        ◆  Temperature Trigger Option:
        ◆  Temperature rising from cold to hot: H suffix
        ◆  Temperature falling from hot to cold: C suffix
        ◆  Output Structure:

             CTS7509, active low with open drain (need an external resistor)
             CTS7510, active low with open drain (no need external resistor)
             CTS7510, active low or high with push-pull 

        ◆  Selectable Hysteresis, 2 oC or 10 oC
        ◆  Temperature Range: -40oC to 125oC

        ◆  Temperature alarm
        ◆  Thermal shutdown
        ◆  Fan control

        ◆  SOT23-5 (CTS7509)
        ◆  SOT23-6 (CTS7510)

        Typical Application

        Typical application in single device

        Typical application in multiple devices

        OUT pin vs. Temperature changing (rising/falling) Relationship

        RSET vs. TSET on equation1 and equation2

        Ordering Information

        CTS7509, output A can be setup as active low with open drain only (require an external pull-up resistor);
        CTS7510, output B can be setup as active low with push-pull, or active high with push-pull, or active low with open drain output (built-in internal pull-up resistor, no require an external pull-up resistor any more).
