Detailed Description

SETPOINT register bit definitions (per channel)

15-bit current setpoint with auto-limit disable.

Current Calculation:

  • Single mode: I_set = 2A * TARGET / 32767
  • Parallel mode: I_set = 4A * TARGET / 32767

Current Capability (per datasheet):

  • Single channel:
    • Typical continuous: ~1.5 A
    • Absolute maximum (register scale): 2.0 A
  • Parallel channels (paired):
    • Typical continuous: ~2.7 A
    • Absolute maximum (register scale): 4.0 A
Warning
The driver uses the full register scale (2A/4A) as maximum setpoint values, but the device will naturally limit to its thermal/electrical capacity (~1.5A single, ~2.7A parallel). Setting higher values may result in current regulation at the device limit rather than setpoint.
Bit Map:
* Bit 15    : AUTO_LIMIT_DIS - Auto-limit disable
* Bits 14-0 : TARGET - Current setpoint value
*
