PROGRAMMABLE LOAD CONTROL REGISTER

Address: 0x010, Reset: 0x0000, Name: PL_CTRL

Configures the programmable load into low idle mode or high idle mode.

0: low idle state. In low idle state, the programmable load current is configured for PL_LOW_CODE when

the channel ADC code is greater than zero but less than the RISE_THR bit field. When the channel

ADC value rises above the PL_RISE_THR, the load current is set to PL_HIGH_CODE.

1: high idle state. In high idle state, the programmable load current is set to PL_HIGH_CODE when

the channel ADC code is higher than zero. The programmed load current flows as soon as there is

enough voltage headroom on the LOAD1 pin.

PROGRAMMABLE LOAD RISE THRESHOLD REGISTER

Address: 0x011, Reset: 0x001E, Name: PL_RISE_THR

Sets programmable load rising edge ADC sample threshold.

RISE_THR

Rising Edge Threshold. When configured in low idle mode, with PL_MODE = 0, when the ADC

value is greater than RISE_THR, the LOAD1 pin is configured to sink a high current

(PL_HIGH_CODE).

0x1E

R/W

The minimum value that can be written is 0x01 and the maximum value is 0xFE. These values are

enforced by the hardware such that a write of 0x00 becomes 0x01 and 0xFF becomes 0xFE.

PROGRAMMABLE LOAD LOW CODE REGISTER

Address: 0x012, Reset: 0x001E, Name: PL_LOW_CODE

Programmable load low code.

LOW_CODE

Programmable Load Low Code. Minimum low current value is in units of 100 µA. The minimum

value is 0x1. If 0x0 is written, LOW_CODE = 0x1.
