TPS65014

SLVS551 – DECEMBER 2004

These devices have limited built-in ESD protection. The leads should be shorted together or the device

placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.

The serial interface can be used for dynamic voltage scaling, for collecting information on and controlling the

battery charger status, for optionally controlling 2 LED driver outputs, a vibrator driver, masking interrupts, or for

disabling/enabling and setting the LDO output voltages. The interface is compatible with the fast/standard mode

2C™ specification allowing transfers at up to 400 kHz.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(1)

The TPS65014 is housed in a 48-pin QFN package with exposed leadframe on the underside. This

7 mm

× 7 mm package exhibits a thermal impedance (junction-to-ambient) of 33 K/W when mounted

on a JEDEC high-k board.

(2)

Consideration needs to be given to the maximum charge current when the assembled application

board exhibits a thermal impedance which differs significantly from the JEDEC high-k board.
