TCK303G,LF(S

TCK303G,LF(S is a 28V high input voltage single input single output load switch IC. It has over voltage protection function featuring low switch ON resistance, high output current and wide input voltage operation. Switch ON resistance is only 73mohm at 4.5V, - 1.0A load conditions. And this features a slew rate control driver, thermal shutdown and FLAG function. Also it can block reverse current if switch turned off. Thus, this is suitable for power management such as battery charge application. This device is available in 0.5mm pitch ultra small package WCSP9. Thus this devices is ideal for portable applications that require high-density board assembly such as cellular phone.

• 15.5V typ over voltage lockout, active low (active-low CE) function, active high VCT function
• Pull up VCT resistance, high input voltage: VIN (max) = 28V
• High output current: IOUT (DC) = 3.0A
• Low ON resistance : RON = 73mohm (Typ.) at VIN = 4.5V, IOUT = - 1.0A
• Under voltage lockout: 2.9V (typ)
• FLAG indicates, internal 15ms startup hold
• Reverse current blocking (SW OFF state), inrush current reducing circuit
• Thermal shutdown function
• WCSP package, operating temperature range from -40 to 85°C
