description (continued)
To promote better system reliability during power up, voltage sequencing and protection are controlled such that
the core and I/O power up together with the same slow-start voltage. At power down, the LDO and ripple
regulator are discharged towards ground for added protection. The TPS56302 also includes inhibit, slow-start,
and under-voltage lockout features to aide in controlling power sequencing. A tri-level voltage identification
definition (VID) sets both regulated voltages to any of 9 preset voltage pairs from 1.3 V to 3.3 V. Other voltages
are possible by implementing an external voltage divider. Strong MOSFET drivers, with a typical peak current
rating of 2-A sink and source are included on chip, which allows paralleling MOSFETs to be driven and allowing
higher current to be controlled. The high-side driver features a floating bootstrap driver with an internal bootstrap
synchronous rectifier. Many protection features are incorporated within the device to ensure better system
integrity. An open-drain output power good status circuit monitors both output voltages, and is pulled low if either
output falls below the threshold. An over current shutdown circuit protects the high-side power MOSFET against
short-to-ground faults, while over voltage protection turns off the output drivers and LDO controller if either
output exceeds its threshold. Under voltage protection turns off the high-side and low-side MOSFET drivers and
the LDO controller if either output is 25% below V
REF
. Lossless current-sensing is implemented by detecting
the drain-source voltage drop across the high-side power MOSFET while it is conducting. The TPS56302 is fully
compliant with TI DSP power requirements.

0 = ground (GND), 1 = floating(VBIAS/2), 2 = (VBIAS)
§
RR = Ripple Regulator, LDO = Low Drop-Out Regulator
VBIAS/2 is internal, leave the VID pin floating. Adding an external 0.1-
μ
F capacitor to ANAGND may be used
to avoid erroneous level.
#External resistors may be used as a voltage divider (from VOUT to VSEN
–
xx to ground) to program output
voltages to other values.
