TCK101G/102G TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCK101G, TCK102G 1A Load Switch IC with Slew Rate Control Driver The TCK101G and TCK102G are load switch ICs for power management with slew rate control driver featuring wide input voltage operation from 1.1 to 5.5 V. Switch ON resistance is only 55 mΩ typical at 3.3 V, 500 mA load condition and these feature a slew rate control driver and thermal shutdown. TCK101G has output auto-discharge function. Maximum Output current type is available up to 1 .0A (DC). This device is available in 0.4 mm pitch ultra small package WCSP6B (0.8 mm x 1.2 mm, t: 0.64 mm (max)). Thus this device is ideal for portable applications that require high-density board assembly such as cellular phone. WCSP6B Weight: 1 mg (typ.) Feature • Wide input voltage operation: VIN = 1.1 to 5.5 V • Low ON resistance : RON = 50 mΩ (typ.) at VIN = 5.0 V, 500 mA RON = 55 mΩ (typ.) at VIN = 3.3 V, 500 mA RON = 75 mΩ (typ.) at VIN = 1.8 V, 500 mA RON = 120 mΩ (typ.) at VIN = 1.2 V, 500 mA • Low Quiescent Current: IQ = 8 μA (typ.) at VIN = VCT = 5.5 V, IOUT = 0 mA • Low standby current: IQ(OFF) = 0.07 μA (typ.) at OFF state • Inrush current reduction circuit • Thermal Shutdown function • Auto-discharge (TCK101G) • Pull down connection between CONTROL and GND • Ultra small package : WCSP6B (0.8mm x 1.2mm, t: 0.64mm(max)) Start of commercial production 2012-08 1 2014-03-01 1 page TCK101G/102G AC Characteristics (Ta = 25°C) VIN = 1.2 V Characteristics Symbol Test Condition(Figure 1) VOUT rise time VOUT fall time Turn on delay Turn off delay tr tf tON tOFF RL = 500 Ω , CL = 0.1 μF RL = 500 Ω , CL = 0.1 μF RL = 500 Ω , CL = 0.1 μF RL = 500 Ω , CL = 0.1 μF TCK101G TCK102G VIN = 3.3 V Characteristics VOUT rise time VOUT fall time Turn on delay Turn off delay Symbol Test Condition(Figure 1) tr tf tON tOFF RL = 500 Ω , CL = 0.1 μF RL = 500 Ω , CL = 0.1 μF RL = 500 Ω , CL = 0.1 μF RL = 500 Ω , CL = 0.1 μF TCK101G TCK102G Min Typ.
