FREQ_SEL[1]

Frequency Selection

Settings for SMPS

00: 125kHz

01: 250kHz

10: 500kHz

11: 1MHz

Operation Frequency Settings

Note: These can NOT be changed “on the fly”

and each setting requires a different inductor

value and capacitors and compensation

components.

CARE SHOULD BE TAKEN WHEN WRITING

TO THIS REGISTER TO AVOID CHANGING

THE FREQUENCY WHILE OPERATING

FREQ_SEL[0]

DIS_SHIP_RENTER

0: Enable re-enter ship

mode

1: Disable ship mode re-

enter

If set to 0, writing to SHIPM_ENTER (Reg 0x00h

Bit 5) allows the IC to re-enter ship mode. If set to

1, the IC ignores the SHIPM_ENTER command.

OTG_HOT[1]

00: VTH55C at 55°C

01: VTH60C at 60°C

10: VTH65C at 65°C

11: Disable shutdown

OTG mode or Disable JEITA Mode Hot

Temperature Monitor TH / NTC Thresholds

OTG_HOT[0]

OTG_COLD

0: VTH0C at 0°C

1: VTH-10C at -10°C

OTG mode or Disable JEITA Mode Cold

Temperature Monitor TH / NTC Thresholds

TREG[1]

00: Disable

01: 80°C

10: 100°C

11: 120°C

Die temperature regulation threshold
