Renesas SLG59M610V

Overview

SLG59M610V from Renesas is a single-channel N-channel high-side load switch optimized for 2.5 V to 5.5 V power rail control, delivering 4 A continuous current with 22 mΩ R_DS(ON), reverse-current blocking, adjustable inrush control via external capacitor, and integrated thermal shutdown, current limiting, and undervoltage lockout - deployed in portable consumer electronics and enterprise computing power domains.

For engineers reviewing the SLG59M610V datasheet, SLG59M610V pinout, SLG59M610V application, or SLG59M610V equivalent, key selection criteria include its TDFN-8 (1.5 × 2.0 mm) package, -40 °C to +85 °C industrial temperature rating, active-high ON/OFF control, and support for output discharge - all critical for space-constrained, thermally sensitive high-side switching designs.

Technical Context

The SLG59M610V integrates a proprietary N-channel MOSFET with an internal charge pump to enable full enhancement at low input voltages (down to 2.5 V), eliminating the need for external gate drive circuitry. Its ramp control is capacitor-set, enabling precise inrush current management during power-up sequences.

Protection architecture includes four confirmed features: adjustable active current limit (ACL), fixed short-circuit current limit (SCL), thermal shutdown with auto-restart (TSD), and true reverse-current blocking (RCB) using back-to-back FET configuration - all implemented without external components.

FAQ

What is the maximum continuous current rating for SLG59M610V?

The SLG59M610V supports 4 A continuous drain current (I_DS) at T_A = 25 °C with proper PCB thermal design. Derating applies above 25 °C ambient; full 4 A operation is guaranteed up to +85 °C case temperature when mounted on a 2-layer 1 oz Cu PCB with ≥100 mm² thermal pad copper area. SLG59M610V thermal performance is validated per JEDEC JESD51-7 standards.

Does SLG59M610V support reverse-voltage detection (RVD)?

No, SLG59M610V does not include reverse-voltage detection. Its protection suite comprises ACL, SCL, TSD, and RCB - but RVD is explicitly absent per Renesas GreenFET Selection Guide documentation. For applications requiring RVD, consider SLG59M1649V or SLG59M1748C, which list RVD in their protection feature columns. SLG59M610V relies on RCB alone to prevent reverse conduction.

Can SLG59M610V operate with a 1.8 V input supply?

No, SLG59M610V requires minimum 2.5 V on the IN pin to ensure proper charge pump operation and MOSFET enhancement. At 1.8 V input, the internal charge pump cannot generate sufficient gate voltage, resulting in incomplete turn-on and elevated R_DS(ON). The device will assert undervoltage lockout (UVLO) below ~2.3 V, disabling the switch. SLG59M610V is not rated for sub-2.5 V operation.

Is the output discharge function of SLG59M610V configurable?

Yes, the output discharge function in SLG59M610V is enabled by connecting the DIS pin to GND; leaving DIS open disables discharge. This hardware-selectable behavior allows designers to retain V_OUT voltage during disable for hold-up or state retention, or actively discharge for fast reset and leakage prevention - without requiring firmware control or external circuitry. SLG59M610V implements this via an internal NMOS FET tied to OUT.

What is the purpose of the SET pin on SLG59M610V?

The SET pin on SLG59M610V connects to an external capacitor that controls the output voltage slew rate during turn-on, directly setting inrush current magnitude and duration. A typical 1 nF capacitor yields ~3 ms ramp time; larger values increase soft-start duration linearly. This capacitor-based method replaces resistor dividers or digital programming, simplifying layout and eliminating calibration overhead. SLG59M610V's SET pin interface is electrically isolated from internal bias rails to ensure stability.
