    Switching Power Manager with USB On-The-Go & Overvoltage Protection

    July 7, 2009
    Linear Technology Corporation announces the LTC4160 and LTC4160-1, a family of power manager ICs for single-cell Li-Ion/Polymer battery-based applications, including media players, personal navigation devices, digital cameras, PDAs and smart phones.

    Linear Technology Corporation announces the LTC4160 and LTC4160-1, the latest members in a family of power manager ICs for single-cell Li-Ion/Polymer battery-based applications, including media players, personal navigation devices, digital cameras, PDAs and smart phones. The LTC4160/-1 features a bidirectional switching power manager which can power an application and charge the battery from USB. Operating in reverse, the same switching regulator can take power from the battery to generate 5V and deliver up to 500mA for USB On-The- Go (OTG) applications without any additional components. The LTC4160/-1 includes automatic load prioritization when powered from USB, input overvoltage protection, a standalone battery charger, and an ideal diode, all in a compact, ultralow profile (0.55mm) 3mm x 4mm UTQFN package. The LTC4160-1 offers a 4.1V battery float voltage, allowing high temperature safety margin, while the LTC4160 features a 4.2V final charge voltage for optimized battery run time.

    The on-chip switching regulator also features programmable input current limits of 100mA and 500mA for enhanced USB compatibility, as well as a wall adapter input current limit setting up to 1.2A. For fast charging, the LTC4160/-1 converts nearly all of the 2.5W available from the USB port to charging current, enabling up to 600mA of charge current from a 500mA limited USB supply and up to 1.2A of charge current from a wall adapter. The device provides an overvoltage protection (OVP) control circuit that prevents damage to its input from the accidental application of high transient voltages. The OVP circuit can protect the USB port even when the IC is providing power for USB OTG.

    The LTC4160 and LTC4060-1 are available from stock in a compact, ultrathin (0.55mm) 3mm x 4mm 20-pin QFN package. Pricing starts at $2.85 each for 1,000-piece quantities. For more information, visit www.linear.com.
