Renesas SLG59H1016V

Overview

SLG59H1016V from Renesas Electronics is a high-voltage, self-powered NMOS load switch with 13.1 mΩ R_DSON at 22 V, 3.5 A continuous current rating, -40 °C to 125 °C operating range, and integrated VIN overvoltage lockout select (4 thresholds) and analog MOSFET current monitor output (10 µA/A). It serves as a protected power-rail switching element in point-of-load distribution for telecom and computing systems.

For engineers reviewing the SLG59H1016V datasheet, SLG59H1016V pinout, SLG59H1016V application, or SLG59H1016V equivalent, key selection considerations include its 4.5–22 V input range, programmable active current limit via RSET, 18-pin STQFN package thermal performance (θ_JA = 40 °C/W), and fault signaling with SOA protection threshold of 5 W.

Technical Context

The SLG59H1016V 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 4.5–22 V and -40 °C to 125 °C. Its state machine implements dual-stage current limiting-resistor-adjustable active limit (2.8–3.6 A typical) and fixed short-circuit limit (0.5 A)-plus automatic 5 W SOA shutdown with 160 ms auto-recovery.

Control logic includes level-sensitive CMOS ON, SEL0/SEL1 inputs for VIN OVLO threshold selection (6 V / 10.8 V / 14.4 V / 24 V), open-drain FAULT output with 80 µs assertion time, and capacitor-adjustable slew rate via CAP pin (10–20 nF). The IOUT analog monitor provides 10 µA/A output with 45 µs response time and 0.5–4 V compliance range.

FAQ

What is the maximum continuous current rating for the SLG59H1016V?

The SLG59H1016V has a maximum continuous current rating of 3.5 A at TJ < 150 °C. This rating assumes proper PCB layout with adequate copper area and thermal vias. At elevated ambient temperatures or with reduced copper, derating applies - e.g., at 85 °C ambient and standard 1 oz. FR-4, the device sustains 3.5 A with θ_JA = 40 °C/W. The datasheet also specifies a 4 A peak pulsed current (pulse width < 1 ms).

How does the SLG59H1016V implement overvoltage protection?

The SLG59H1016V implements VIN overvoltage lockout (OVLO) via two CMOS input pins - SEL0 and SEL1 - which select one of four fixed thresholds: 6 V, 10.8 V, 14.4 V, or 24 V. When VIN exceeds the selected threshold, the internal state machine opens the FET and asserts the FAULT pin within 80 µs. The OVLO remains active until VIN falls below the hysteresis band (typically ~0.3 V), ensuring noise immunity and stable recovery.

What is the function and accuracy of the IOUT pin on the SLG59H1016V?

The IOUT pin on the SLG59H1016V delivers an analog current output proportional to the main FET's load current, with a nominal gain of 10 µA/A. Accuracy is ±10% over 0.5–3.5 A and ±15% over full temperature range (-40 °C to 125 °C). The output has 0.5–4 V compliance range and responds to current changes in 45 µs (0–90%), enabling real-time monitoring when converted to voltage via a grounded sense resistor.

Can the SLG59H1016V be used without an external RSET resistor?

No - the SLG59H1016V requires an external 1%-tolerance metal-film resistor connected to the RSET pin (Pin 18) to define its active current limit. Without RSET, the device defaults to internal short-circuit current limiting only (0.5 A), disabling programmable overcurrent protection. Valid RSET values range from 23.5 kΩ (4 A limit) to 91 kΩ (1 A limit); values outside this range result in undefined or non-compliant current limiting behavior.

What package type and dimensions does the SLG59H1016V use?

The SLG59H1016V uses an 18-pin STQFN (Super Thin Quad Flat No-lead) package measuring 1.6 mm × 3.0 mm with 0.40 mm pitch. It conforms to JEDEC MO-220, variation WCEE, and features fused VIN (pins 4–8) and VOUT (pins 9–13) terminals for low-inductance, high-current routing. The package is RoHS-compliant, halogen-free, and rated for reflow per IPC/JEDEC J-STD-020.
