SLG59M1641V
Description
The SLG59M1641V is a dual-channel, 45mΩ PMOS load switch designed to switch 1.5V to 5.5 V power rails up to 2A in each channel. When either channel is enabled, reverse‑current protection will quickly open the switch in the event a reverse‑voltage condition is detected (a VOUT > VIN + 50mV condition opens the switch). If the channel’s VIN voltage is too low, the load switch also contains an internal UVLO threshold monitor to keep or to turn the switch OFF. Each load switch is independently controlled via its own low-voltage compatible CMOS input. Designed to operate over a -40 °C to 85 °C temperature range, the SLG59M1641V is available in a RoHS-compliant, ultra‑small 1.6mm x 1.0mm 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 911 KB Feb 22, 2019AI-generated Summary: Extending the maximum operating current of GreenFET load switches can be achieved by using two lower-current devices in parallel, maintaining protection features and reducing overall RDSON. Parallel operation balances current sharing due to low RDSON variation in Renesas's MOSFET design. Examples include using pairs of SLG59H1006V and SLG59M1714V devices, with detailed operational waveforms and recommended PCB layouts provided. High-current single devices like SLG59M1568V are also covered. The document includes application diagrams, oscilloscope captures, and design guidelines for high-current load switch applications.
- Application NotePDF 301 KB May 11, 2017AI-generated Summary: Multiplexing two power rails to a common output is achieved using Renesas’ GreenFET load switches, specifically the dual-channel SLG59M1639V or single-channel SLG59M1748C devices. These switches handle 1.5V to 5V power rails up to 2-2.2A, provide true reverse current blocking, and fast detection to prevent voltage drops and reverse current flow. Proper control of ON signals ensures smooth switchover between power sources, minimizing transient disturbances. Increasing load capacitance or resistance can reduce voltage drop during switching. This solution suits consumer electronics like tablets and smartphones, enabling seamless switching between internal batteries and external power supplies.
