TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic

TCK321G, TCK322G

36 V, Dual Inputs – Single Output Power Multiplexer IC

with Over Voltage Protection

The TCK321G and TCK322G are 36 V high input voltage Dual

Inputs-Single Output multiplexer load switch ICs. It has Over Voltage

Protection featuring low switch ON resistance, high output current

and wide input voltage operation. Switch ON resistance is only 98

m

Ω at 4.5 V, - 1.0 A load conditions. And these feature a slew rate

control driver, thermal shutdown and flag function. Also it can block

reverse current if switch turned off. Output current is available up to

2.0 A per channel. Thus this is suitable for power management

selector such as Battery Charge application.

This device is available in 0.5 mm pitch small package WCSP16C

(1.9 mm x 1.9 mm, t: 0.5 mm (typ.)).Thus this devices is ideal for

portable applications that require high-density board assembly such

as mobile phone.

Feature

• Over Voltage Lockout : 12.0 V, 15.0 V (typ.)

• Under Voltage Lockout: 2.9 V (typ.)

• Reverse current blocking per channel(SW OFF state)

• Inrush current reducing circuit.

• Auto selection mode

• Manual selection mode

• Break Before Make switch

• Thermal Shutdown function

• Small package: 0.5 mm pitch WCSP16C (1.9 mm x 1.9 mm, t: 0.5 mm (typ.)), PD = 1.65 W
