BL1532—DPDT USB2.0 Analog Switch
Low-Power, Two-Port, High-Speed, USB2.0 (480Mbps)
DPDT Analog Switch BL1532
Description
The BL1532 is a Low-Power, Two-Port, High-Speed, USB2.0 (480Mbps) double –pole double-throw
(DPDT) Analog Switch featuring an On-Resistance of 4.5 ohm at VCC=3V and a Low On Capacitance
3.7pf Typical.
The BL1532 is compatible with the requirements of USB2.0 and the wide bandwidth needed to pass the
third harmonic, resulting in signals with minimum edge and phase distortion. Superior channel-to
channel crosstalk also minimizes interference. Break-before-make function for both parts eliminates
signal disruption during switching from preventing both switches being enabled simultaneously.
The BL1532 contains special circuitry on the switch I/O pins for applications where the VCC supply is
powered-off (VCC=0), which allows the device to withstand an over-voltage condition. This device is
designed to minimize current consumption even when the control voltage applied to the Sel pin is lower
than the supply voltage (VCC). This feature is especially valuable to ultra-portable applications, such as
cell phones, allowing for direct interface with the general purpose I/Os of the baseband processor. Other
applications include switching and connector sharing in portable cell phones, PDAs, digital cameras,
printers, and notebook computers.

Note:
(1) Typical characteristics are at +25°C
(2) Measured by the voltage drop between Dpn/Dnn and Dp/Dn pins at the indicated
current through the switch. On resistance is determined by the lower of the voltage on
the two (Dpn/Dnn and Dp/Dn ports).
(3) △ RON= RON(MAX) – RON(MIN), between Dp and Dn .
