FSA5157 0.4 Low Voltage SPDT Analog Switch
January 2007
FSA5157 0.4 Low Voltage SPDT Analog Switch
General Description
The FSA5157 is a low ON Resistance, low power Single Pole Double Throw (SPDT) analog switch. This product has been designed for switching audio signals in applications such as cell phones and portable media players. The ultra-low 0.43/4 impedance, sub 1A current consumption, and 1.65V to 4.3V operating voltage range makes this product ideal for battery powered applications. The FSA5157 also features bi-directional operation and make-before-break functionality. This device is fully specified for operation at 1.8V, 2.5V and 3.3V. A growing number of applications require the voltage applied to the select input to be lower then the VCC applied. Under this condition, most switches would typically consume over 100A of current. This would be an unacceptable level for battery powered applications. The FSA5157 has been designed to minimize current consumption under this condition. The ICCT is specified for <12A under a worse case condition of VCC = 4.3V and VIN = 1.8V.
Features
Typical 0.4 On Resistance (RON) for +2.7V supply FSA5157 features less than 12A ICCT current
when S input is lower than VCC
0.25 maximum RON flatness for +2.7V supply 1.0mm x 1.45mm 6-Lead Pb-Free MicroPakTM
package
Broad VCC operating range: 1.65V to 4.3V Low THD (0.02% typical for 32 load) High current handling capability
(350mA continuous current under 3.3V supply)
Control logic is 1.8V CMOS logic compatible
Applications
Cellular phone PDA Portable Media Player

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
