Low-voltage rail switching in a 1 mm² footprint
The SLG59M1551V is a single-channel high-side load switch from Renesas, designed for sub-2V core power rails. Its 0.85V to 1.9V supply range (Vcc/Vdd) means it directly switches a 1.2V or 1.8V processor or FPGA core rail without an external level translator — the CMOS input enable pin tracks the same voltage domain.
The 4-STDFN (1x1 mm) package — supplier device package 4-STDFN (1x1) — is a four-lead, 1 mm² footprint. The centre pad is the main thermal and electrical path for the output; the PCB layout must route the output trace from the pad with adequate copper width for 2A without exceeding a 30°C temperature rise. Surface-mount assembly with standard lead-free reflow profiles. The Tape & Reel (TR) option is the production-reel quantity; Cut Tape (CT) is available for prototype or low-volume builds without committing to full-reel inventory. The single output is configured as a high-side N-Channel switch, so the load connects between the output pin and ground.
Active lifecycle and compliance position
It is RoHS Compliant, with no RoHS exemption expiry to schedule for compliance reviews. No pin-compatible second-source or successor is recorded — the BOM position is single-sourced to this order code.
