The TCK2292xG and TCK2297xG 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 25 mΩ

typical at 5.0 V, -0.5 A load condition and these feature a slew rate control

driver. TCK2292xG has output auto-discharge function. Output current

type is available on 2 A.

These devices are available in 0.4 mm pitch ultra small package

WCSP6E (0.8 mm x 1.2 mm, t: 0.55 mm) .Thus they are ideal for portable

applications that require high-density board assembly such as cellular

phone.

Feature

 Wide input voltage operation: VIN = 1.1 to 5.5 V

 Low ON resistance:

RON = 25 mΩ (typ.) at VIN = 5.0 V, IOUT = -0.5 A

RON = 31 mΩ (typ.) at VIN = 3.3 V, IOUT = -0.5 A

RON = 52 mΩ (typ.) at VIN = 1.8 V, IOUT = -0.5 A

RON = 104 mΩ (typ.) at VIN = 1.2 V, IOUT = -0.5 A

 Low Quiescent Current: IQ = 0.1 μA (typ.) at IOUT = 0 mA(TCK22921G, TCK22971G)

 Slew Rate Control circuit

 Output auto-discharge (Option)

 Reverse current blocking (VIN = 0 V)

 Pull down connection between Control and GND(Option)

 Ultra small package: WCSP6E (0.8mm x 1.2mm, t: 0.55mm)
