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

Function Documentation

CalculateCurrent()

constexpr uint16_t tle92466ed::SETPOINT::CalculateCurrent ( uint16_t  target, bool  parallel_mode = false  )

constexprnoexcept

Calculate current from setpoint value.

Parameters

target	Setpoint register value
parallel_mode	true if channel is in parallel mode

Returns

Current in milliamperes

Note

Uses rounding to minimize quantization error (adds half of 32767 before division)

CalculateTarget()

constexpr uint16_t tle92466ed::SETPOINT::CalculateTarget ( uint16_t  current_ma, bool  parallel_mode = false  )

constexprnoexcept

Calculate setpoint value for desired current.

Parameters

current_ma	Desired current in milliamperes (0-2000 single, 0-4000 parallel)
parallel_mode	true if channel is in parallel mode

Returns

Setpoint register value

Note

Uses rounding to minimize quantization error (adds half of max_current before division)

CalculateTargetUa()

constexpr uint16_t tle92466ed::SETPOINT::CalculateTargetUa ( uint32_t  current_ua, bool  parallel_mode = false  )

constexprnoexcept

Calculate setpoint value for a desired current in microamperes.

TARGET is 15-bit: one LSB is 2000 mA / 32767 ≈ 61 µA (single) or 122 µA (parallel). The mA overload throws that resolution away, which matters for proportional valves whose flow moves 1–2 slpm per mA. Rounds to nearest, saturates at MAX_TARGET.

Parameters

current_ua

Desired current in µA (0–2 000 000 single, 0–4 000 000 parallel).
