Renesas SLG59H1006V

Overview

SLG59H1006V from Renesas Electronics is a high-voltage, self-powered NMOS load switch optimized for 4.5 V to 22 V power rails delivering up to 5 A continuous current. It features 13.1 mΩ R_DSON at 22 V, pin-selectable VIN overvoltage lockout (6 V / 10.8 V / 14.4 V / 24 V), and an analog MOSFET current monitor output (10 µA/A) for real-time load diagnostics in point-of-load distribution.

For engineers reviewing the SLG59H1006V datasheet, SLG59H1006V pinout, SLG59H1006V application, or SLG59H1006V equivalent, this device supports precise inrush control via external CAP capacitor, dual-stage current limiting (resistor-adjustable active limit + internal short-circuit protection), and fast 4 kΩ output discharge - critical for reliable power sequencing in telecom and computing systems.

Technical Context

The SLG59H1006V integrates a proprietary high-voltage GreenFET with copper pillar interconnects to maintain stable R_DSON (<0.05 mΩ/V ΔR_DSON/ΔV_IN, <0.06 mΩ/°C ΔR_DSON/ΔT) across its full 4.5–22 V input range. Its state machine implements automatic SOA protection triggered at 5 W dissipation for >2.5 ms, plus thermal shutdown at 125 °C with hysteresis (restart at 100 °C).

Control logic includes CMOS-compatible ON input (VIH > 0.9 V), dual SEL pins for 4-level OVLO selection, open-drain FAULT signaling with 80 µs assertion time, and IOUT analog monitoring with 45 µs response to 0–2.4 A step load. The 18-pin STQFN package (1.6 × 3.0 mm, 0.4 mm pitch) uses fused VIN/VOUT pins to minimize trace resistance and thermal impedance (θ_JA = 40 °C/W).

FAQ

What is the maximum continuous current rating for the SLG59H1006V?

The SLG59H1006V is rated for 5 A continuous current at T_J < 150 °C. This rating assumes proper PCB layout with 2 oz copper, adequate thermal vias, and adherence to the recommended 1.6 × 3.0 mm STQFN landing pattern. At 85 °C ambient, the 13.1 mΩ R_DSON yields ~327 mW conduction loss, which the 40 °C/W θ_JA package can dissipate with appropriate board-level thermal design. The SLG59H1006V also supports 6 A peak current for pulses under 1 ms.

How does the SLG59H1006V implement overvoltage lockout?

The SLG59H1006V provides four selectable VIN overvoltage lockout thresholds - 6 V, 10.8 V, 14.4 V, and 24 V - configured via the binary combination of SEL0 and SEL1 pins. When VIN exceeds the selected threshold, the internal state machine immediately opens the MOSFET and asserts the FAULT pin within 80 µs. The lockout remains active until VIN falls below the threshold and the ON pin is toggled; the undervoltage lockout (UVLO) is fixed at 2.4–3.8 V and cannot be adjusted.

Can the SLG59H1006V monitor load current without external components?

The SLG59H1006V provides an analog current monitor output (IOUT) that delivers 10 µA per ampere of MOSFET current, with ±7% accuracy over 0.5–5 A. To convert this to a measurable voltage, a grounded resistor (e.g., 84.5 kΩ for 0.845 V/A) is required at the IOUT pin, along with a 180 pF bypass capacitor to GND for optimal linearity. No additional op-amps or ADC references are needed - the SLG59H1006V itself generates the proportional current signal.

What is the purpose of the CAP pin on the SLG59H1006V?

The CAP pin on the SLG59H1006V connects to an external ceramic capacitor (10–20 nF) that sets the VOUT slew rate and total turn-on time. For example, a 10 nF capacitor yields ~3.2 V/ms slew rate at 22 V input. This capacitor controls inrush current into capacitive loads, ensuring monotonic VOUT ramping and preventing false triggering of SOA or current-limit protection during startup - especially critical in systems with large output capacitance like telecom line cards.

Does the SLG59H1006V include thermal protection?

Yes, the SLG59H1006V includes integrated thermal protection that shuts down the MOSFET when junction temperature exceeds 125 °C (THERMON), and automatically resumes operation once temperature drops to 100 °C (THERMOFF). This hysteresis prevents oscillation near the trip point. Additionally, the device implements Safe Operating Area (SOA) protection triggered by power dissipation exceeding 5 W for more than 2.5 ms - a distinct mechanism that responds to combined voltage/current stress, not just temperature alone.
