REQ-006 — CC limit linearity ≤ ±0.1% FS over active ISET range
approved · Performance · Approved by demo
Statement
The constant current limit shall be linearly proportional to the ISET DAC voltage over the active control range (0–1.5A).
Acceptance Criteria
ISET swept over active range (0.20V–4.56V); measured current limit vs ISET; residual non-linearity ≤ ±0.1% of full scale (1.5A) = ±1.5mA; resolution ≈ 0.42mA/step (3,571 usable DAC steps).
