The TPS2066CDGN-2 is a Power Distribution Switch (PDS), Load Driver (LD) part of the Texas Instruments Power Management Integrated Circuit (PMIC) family. It is designed to provide power management and switching of up to nine loads simultaneously, in a variety of applications. The device features a low-side DMOS switch with low on-resistance, a low output voltage drop, and low leakage current. It also features an operating frequency of 2MHz and a quiescent current of less than one microamp.

The device is suitable for a variety of applications, including motor control, LCD backlight, LED lighting, and other motor power applications that require fast, reliable switching. In motor control applications, the TPS2066CDGN-2 can provide power management and switching for up to nine motors from one integrated device, reducing board space and complexity. The device can be used to switch between multiple power sources, such as USB, battery and AC sources, helping to reduce system cost.

The TPS2066CDGN-2 features an integrated P-Channel power switch, allowing low side control of motors, LEDs, and other devices that require a low side switch. The device also features a low-side junction-FET driver, allowing it to efficiently drive N-channel MOSFETs with turn-off times of below 5ns. This feature reduces power loss associated with the driver’s internal resistance, enabling the device to provide excellent over-current protection without compromising efficiency.​

The TPS2066CDGN-2’s operating voltage range is from 2.7V to 5.5V, and its maximum switch current is 2A. Its ESD protection level is 8kV, and it is Pb free and RoHS compliant. The device also features low voltage lock-out for increased safety, thermal protection for overtemperature conditions, and over-current protection with a short circuit current limit of 2.5A.

The TPS2066CDGN-2’s main strength is its ability to provide power management and switching for up to nine loads simultaneously. It can handle a wide range of applications including motor control, LCD backlight, LED lighting and other motor power applications. The device features a low-side junction FET driver, enabling efficient drive of N-channel MOSFETs; low voltage lockout; and thermal, over-current and ESD protection.
