SLG59M1721V
Description
The SLG59M1721V is a high performance 18 mΩ, 2.0 A single‑channel nFET load switch which can operate with a 2.5 V to 3.6 V VDD supply to switch power rails from as low as 0.85 V up to the supply voltage. The SLG59M1721V incorporates two‑level overload current protection, thermal shutdown protection, and in‑rush current control which can easily be adjusted by a small external capacitor. Using a proprietary MOSFET design, the SLG59M1721V achieves a stable 18 mΩ RDSON across a wide input voltage range and over temperature. In addition, the SLG59M1721V’s package also exhibits low thermal resistance for high‑current operation using proprietary CuFET technology. Fully specified over the -40 °C to 85 °C temperature range, the SLG59M1721V is packaged in a space‑efficient, low thermal resistance, RoHS‑compliant 1.0 mm x 1.4 mm STDFN package.

- GuideGreenFET load switches are designed for efficient high‑side power control in low‑voltage applications. These devices combine low RDS(on), compact packaging, and integrated protection features to replace discrete designs, reducing PCB space and improving system reliability. This guide enables engineers to quickly compare key parameters and select the optimal device for their application.
- Application NotePDF 364 KB Jan 16, 2019AI-generated Summary: Unidirectional GreenFET load switches can be configured in pairs to create bidirectional load switches (BLS) that conduct current in both directions while maintaining protection features such as current limiting, short circuit, thermal shutdown, and inrush current control. Two types of BLS implementations are detailed: a low-power solution using SLG59M1558V devices and a high-performance solution using SLG59M1709V devices. The document explains circuit configurations, operation waveforms, and protection mechanisms, enabling cost-effective, compact, and reliable bidirectional switching for portable device power management.
