SLG7SQ47664V 概要
A power management sequencer is an integrated circuit that monitors a primary voltage rail and asserts a secondary enable signal with a programmable delay once that rail crosses a user-defined threshold. Sequencers sit in the supervisory sub-tree of the broader Power Management category between reset/supervisor ICs and full PMICs, providing a simpler, smaller, and lower-cost solution when only turn-on ordering is needed rather than full multi-rail voltage regulation.
Key features of the SLG7SQ47664V include a single sequencing channel with two open-drain outputs, configurable time delay blocks, selectable trigger thresholds for detecting power-good events on the monitored rail, and ultra-low quiescent current consumption tailored for battery-powered designs. The small STQFN-12 footprint occupies only 2.56 mm² of board area, making it appropriate for dense PCB layouts such as wearables, SSDs, and IoT sensor modules.
Technically, the part is designed and verified through the GreenPAK Designer toolchain, which lets engineers program the timing thresholds and delay values without dedicated firmware. Hysteresis on the comparator input prevents chattering near the threshold, and the open-drain output stage lets the device pull either a 3.3 V or 5 V logic rail up to its maximum rated voltage regardless of the IC's own supply.
Typical applications include multi-rail FPGA and SoC power-up sequencing, SSD controller bias-voltage ordering, and battery charging pre-bias protection in portable electronics. The 12-pin STQFN package supports reflow profiles up to 260 °C peak and is compatible with standard lead-free assembly.
When designing in the SLG7SQ47664V, ensure that the pull-up resistors on the open-drain outputs are referenced to the correct downstream rail and that the timing capacitor or internal delay setting is chosen to allow the upstream regulator to stabilize before the next rail is enabled. The exposed thermal pad must be soldered to a ground copper pour of at least 0.5 cm² to meet the rated power dissipation.

主な用途
SLG7SQ47664V の用途: 6 件s: FPGA Multi-Rail Power-Up Sequencing, SSD Controller Bias-Voltage Ordering, Wearable and IoT Sensor Module Power Sequencing, Battery Charger Pre-Bias Protection, Industrial Multi-Supply Module Sequencing, Test and Measurement Board Bring-Up.
FPGA Multi-Rail Power-Up Sequencing
The SLG7SQ47664V solves one of the most common board-design pain points in FPGA-based systems: ensuring that the core rail, the auxiliary rail, and the transceiver rail all power up in the correct order. The part monitors a primary rail through its threshold comparator and, when the rail crosses the user-defined trigger level, asserts two open-drain outputs after a programmable delay that can be set in microseconds to seconds through GreenPAK Designer. Compared to a discrete supervisor IC plus an RC delay chain, the SLG7SQ47664V saves roughly 30 mm² of board area and eliminates tolerance stack-up from passive components. Engineers building PCIe, DDR memory, or high-speed transceiver-based FPGAs use this part to satisfy the absolute-sequencing requirement spelled out in vendor reference designs. The exposed-pad 12-STQFN footprint drops directly next to the FPGA pins without disturbing the surrounding LDO layout.

SSD Controller Bias-Voltage Ordering
Inside an SSD the controller core, NAND interface, and DRAM cache each require distinct supply rails that must come up in a defined sequence to prevent large inrush currents and bus contention. The SLG7SQ47664V's single-channel sequencer with two open-drain outputs is sized precisely for this three-rail problem when one rail can be enabled by direct rail-to-rail drive. The part's small 12-STQFN (1.6 x 1.6 mm) footprint fits inside the BGA shadow of an M.2 SSD, where board area is measured in square millimeters. The GreenPAK Designer configurability lets a single BOM part cover multiple SSD SKUs by changing only the firmware image programmed into GreenPAK. Hysteresis on the comparator input prevents retriggering when the upstream rail dips slightly during downstream load steps.

Wearable and IoT Sensor Module Power Sequencing
Battery-powered wearables and IoT sensor nodes typically need a small main SoC rail followed by a sensor or radio enable, all while minimizing quiescent current drain on the coin-cell or rechargeable battery. The SLG7SQ47664V supports these designs by sitting in series between the battery and the secondary rail enable with two open-drain pull-down outputs that draw no current until asserted. GreenPAK Designer lets the designer pick a delay window long enough to let the main SoC boot before the radio wakes, preventing firmware boot contention. The 12-STQFN with exposed pad is rated for reflow profiles that match standard lead-free wearables assembly lines. Compared to a discrete MOSFET-plus-RC sequencing circuit, the SLG7SQ47664V offers a smaller footprint, factory-trimmed threshold accuracy, and no quiescent current penalty.
おすすめ
Battery Charger Pre-Bias Protection
Battery charger ICs generally require an output enable signal only after the input rail is stable to prevent the charger from trying to source into a discharged or shorted battery. The SLG7SQ47664V's open-drain output can be wired to the charger's CE (charge enable) pin with a pull-up to the battery-side rail, releasing the charger only after the upstream rail crosses the configured trigger threshold. The programmable delay from the GreenPAK Designer project lets the designer add a safety window of tens of milliseconds, ensuring the upstream rail is fully settled before the charger starts. Compared to a pure RC delay the SLG7SQ47664V is independent of capacitor leakage and temperature drift, giving a more reliable pre-bias lockout.

Industrial Multi-Supply Module Sequencing
Industrial PLC and distributed I/O modules often stack 24 V, 5 V, 3.3 V, and 1.8 V rails with strict ordering requirements that mirror the IEC 61131-2 hot-plug profile. The SLG7SQ47664V's single sequencer channel with two open-drain outputs drives the downstream enables for these subsystems after monitoring one primary rail. The exposed-pad STQFN-12 package provides adequate thermal dissipation for the industrial -40 to +85 °C operating range typical of these designs. The Renesas GreenPAK design tool allows time-delay reconfiguration for derivative products without spinning a new PCB layout, accelerating platform reuse across product variants.
おすすめ
Test and Measurement Board Bring-Up
Bench test fixtures and evaluation boards benefit from a sequencing controller that can be re-programmed in seconds to test different power-up profiles. Engineers using the SLG7SQ47664V on a test board can iterate the trigger threshold and time delay entirely from GreenPAK Designer without resoldering passive components. The two open-drain outputs can drive LEDs to indicate sequencing state for visual debugging during bring-up. Compared to fixed-function supervisors, the SLG7SQ47664V's programmability dramatically shortens test-cycle iteration time when validating a new power architecture.

設計ノート
Estimated: the SLG7SQ47664V is housed in a 12-STQFN package with an exposed thermal/ground pad. To meet rated power dissipation, solder the exposed pad to a continuous ground copper pour of at least 0.5 cm². Place input bypass capacitors within 2 mm of the VDD pin to keep the internal timing reference stable and prevent the comparator from seeing supply transients.
Do not leave any input pin (including NC pins) floating if the GreenPAK project does not configure it internally - either tie to ground or to VDD through a 100 kΩ resistor. Floating pins can draw extra current or trigger spurious outputs in CMOS inputs. Confirm the latest GreenPAK Designer project file matches the silicon revision marked on the device before committing the layout to volume production.
The open-drain outputs of the SLG7SQ47664V require external pull-up resistors referenced to the rail being released, not to the IC's own VDD. Choose a pull-up value between 10 kΩ and 100 kΩ depending on speed and current budget: 10 kΩ gives faster edges at the cost of higher quiescent draw, while 100 kΩ saves power at slower edges. Always reference the pull-up rail's voltage to ensure the output signal stays within the downstream enable pin's absolute maximum rating.
