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
mΩ 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.
Weight : 3.9 mg ( typ.)
Feature
• High output current: IOUT (DC) = 2 A, per channel
• Low ON resistance : RON = 98 mΩ (typ.) at VIN = 4.5 V, - 1.0 A, per channel
