6.24 Peak Current (PEAK_CUR)

Address 51

PEAK_CUR sets the boost stage peak current, which assists in configuring the boost output power. The register

value is an unsigned integer in the range of 0

value255 where the LSB = 4.1mA.The peak current can be

configured from 0mA to 1.0455A.

CRC

Configures the communication system to use the CRC value in the CRC_TAG
register (see "CRC Tag (CRC_TAG) – Address 102" on page 50). Enabling
this bit is required when programming the OTP registers of the CS1630/31.

0 = Disables the use of the CRC register
1 = Enables the use of the CRC register

RATE[1:0]

Configures the dimming rate for the external overtemperature protection
(eOTP) feature which decreases the second stage dim level once the mea-
sured 8-bit temperature value corresponding to the external NTC resistance
connected to pin eOTP exceeds the temperature value configured using bits
eOTP[4:0] (Config59[7:3] of Address 91). The rate at which the 12-bit dim
level is decreased is set to any one of the following:

00 = 4 dims per temperature code above CODE

TEMPeOTP

01 = 8 dims per temperature code above CODE

TEMPeOTP

10 = 16 dims per temperature code above CODE

TEMPeOTP

11 = 32 dims per temperature code above CODE
