패키지 = SO Display
타입 = LED Number of Pins = 8 Supply Voltage = 3 ??5.5 V Maximum Supply Current = 1.5A
최소 작동 온도 = -40°C
장착형태 = Surface Mount Width = 4mm
높이 = 1.55mm Length = 5mm The STCS1A is a BiCMOS constant current source designed to provide a precise constant current starting from a varying input voltage source. The main target is to replace discrete components solution for driving LEDs in low voltage applications such as 5 V, 12 V or 24 V giving benefits in terms of precision, integration and reliability. The current is set with external resistor up to 1.5 A with a ± 10 % precision a dedicated pin allows implementing PWM dimming. An external capacitor allows setting the slope for the current rise from tens of microseconds to tens of milliseconds allowing reduction of EMI. An open-drain pin output provides information on load disconnection condition.Slope control with external cap LED disconnection diagnostic Up to 40 V input voltage Up to 1.5 A output current Less than 0.5 V voltage overhead Shutdown pin PWM dimming pin Applications LED constant current supplying for varying input voltages Low voltage lighting Small appliances LED lighting Car LED lights
