Active production, AEC-Q100 qualified
The MAX25221CATJ/V+: AEC-Q100 qualification (Grade 1 implied by the -40°C to +125°C operating range) means the part has passed the full automotive reliability stress battery: temperature cycling, ESD, latch-up, and high-temperature operating life. Tier-one ECU programs can accept it with PPAP documentation from Analog Devices.
Four-channel TFT power rail architecture
This is a four-channel automotive TFT LCD power supply IC — it integrates the gate-drive supply, logic supply, and source-driver rails needed for a center-stack infotainment display or instrument cluster panel. The 2.65 V to 5.5 V input range lets it run from a 3.3 V or 5 V rail common in automotive power trees, or from a battery-backed 3.0 V coin cell during key-off sleep. The 1.5 mA quiescent current is low enough that the part does not dominate the system sleep budget.
32-TQFN exposed-pad footprint
Packaged in a 32-WFQFN with exposed pad (5x5 mm body, 0.5 mm pitch). The thermal pad must be soldered to a PCB copper plane to keep the junction-to-ambient thermal resistance within the datasheet limit — a 2x2 via array under the pad is standard practice. Surface-mount assembly: the 0.5 mm pitch requires a solder-paste stencil aperture matched to the land pattern and a reflow profile that does not exceed the 260°C peak body temperature for the lead-free finish.
ROHS3 compliance and supply posture
ROHS3 compliant — no exemptions for lead in solder or PBB/PBDE flame retardants. The tin-plated termination finish is compatible with standard lead-free reflow profiles. Sourced to order against the BOM quantity through independent distribution.
