Load Switch IC with Current Limit function
The TCK104G and TCK105G are load switch ICs for power
management with slew rate control driver and current limit
function featuring wide input voltage operation from 1.1 to 5.5 V.
Switch ON resistance is only 50 mΩ typical at 5.0V, -700mA load
condition and these feature a slew rate control driver, thermal
shutdown and output auto-discharge function. Output current
type is available on -500mA, and -800mA. Thus it is easy to
select devices and helpful for the design.
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
devices 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: V_IN = 1.1 to 5.5 V
• Low ON resistance :
R_ON = 50 mΩ (typ.) at V_IN = 5.0 V, -700 mA
R_ON = 55 mΩ (typ.) at V_IN = 3.3 V, -700 mA
R_ON = 75 mΩ (typ.) at V_IN = 1.8 V, -700 mA
R_ON = 140 mΩ (typ.) at V_IN = 1.2 V, -700 mA
• Low Quiescent Current: I_Q = 20 μA (typ.) at I_OUT = 0 mA
• Low standby current: I_Q(OFF) = 0.1 μA (typ.) at OFF state
• Current limit function
• Inrush current reducing circuit
• Thermal Shutdown function
• Auto-discharge
• Pull down connection between CONTROL and GND
• Ultra small package : WCSP6B (0.8mm x 1.2mm, t: 0.64mm(max))
