Product details
Overview
PS9531-V-AX from Renesas Electronics is a high-speed, 2.5 A peak output current, 8-pin DIP photovoltaic gate driver IC optimized for IGBT and power MOSFET switching in industrial inverters and induction heating systems. It integrates a GaAlAs LED input stage, photo-diode, signal processing circuit, and power output transistor on a single chip with ±50 kV/μs common-mode transient immunity and UVLO protection with hysteresis.
For engineers reviewing the PS9531-V-AX datasheet, PS9531-V-AX pinout, PS9531-V-AX application, or PS9531-V-AX equivalent, this device is selected for high-reliability isolated gate drive where fast propagation delay (175 ns max), robust noise immunity, and long creepage distance (7 mm) are critical in motor control and power conversion designs.
Technical Context
The PS9531-V-AX implements an optically coupled architecture with integrated UVLO hysteresis (11.0 V turn-on, 9.5 V turn-off) and dual-output-stage transistor logic to ensure clean, rail-to-rail gate drive under transient conditions. Its internal shield and layout minimize capacitive coupling between input and output sides.
It operates across −40°C to +125°C ambient temperature with 15–30 V supply range (VCC–VEE), supports 50 kHz maximum switching frequency, and delivers 2.0–2.5 A peak output current into short pulses (≤10 μs, ≤0.2% duty cycle) while maintaining sub-200 ns propagation delay symmetry (tPHL−tPLH ≤ ±90 ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | 2.5 A MAX - drives large IGBT gates with low Miller plateau voltage drop during hard-switching events |
| Propagation Delay | tPLH/tPHL ≤ 175 ns - enables >5 MHz effective control loop bandwidth in closed-loop inverter applications |
| CMR Immunity | ±50 kV/μs MIN - suppresses false triggering from high dv/dt noise in 600–1200 V IGBT half-bridges |
| UVLO Threshold | VUVLO+ = 12.3 V, VUVLO− = 11.0 V - prevents partial turn-on of power devices during brown-out or startup |
| Isolation Voltage | 5000 Vr.m.s. - meets reinforced insulation requirements for industrial safety standards (UL, CSA, SEMKO) |
| Operating Temp | −40°C to +125°C - supports operation in enclosed motor drive cabinets without derating |
| Package | 8-pin DIP (9.25 × 6.5 mm) - compatible with through-hole assembly and legacy PCB layouts |
Pinout & Package
PS9531-V-AX uses an 8-pin plastic Dual In-line Package (DIP) with standard 2.54 mm pitch, 9.25 mm body length, and 6.5 mm width. Pin 1 is marked by notch or dot; pins 1–4 form the input side, pins 5–8 the output side, with internal shield connected to pin 5 (VEE).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4 | NC (Non-Connection) | Unused; may be left open or tied to GND on input side - no electrical function, but improves noise margin if grounded |
| 2 | Anode | LED anode input - requires 8–12 mA forward current for reliable turn-on; reverse voltage limited to 5 V |
| 3 | Cathode | LED cathode input - referenced to input-side ground; must be driven with controlled rise/fall time ≤0.5 μs |
| 5 | VEE | Output-side emitter reference - internally connected to shield; serves as low-side return for output stage |
| 6 | VO | Power output terminal - delivers 2.5 A peak current to IGBT/MOSFET gate; rated for 0–VCC voltage swing |
| 7 | NC | Non-connection - may be left open or tied to VO or VEE on output side; not used for signal or bypass |
| 8 | VCC | Positive supply for output stage - must be decoupled with ≥1.0 μF capacitor within 10 mm of pins 5/6/8 |
Key Features
| Feature | Design Value |
|---|---|
| UVLO with Hysteresis | 1.3 V hysteresis window ensures stable gate drive during supply ramp-up/down without oscillation |
| High CMR | ±50 kV/μs immunity allows direct placement near high-power switching nodes without external filtering |
| Fast Switching | 175 ns max tPLH/tPHL and 40 ns rise/fall times support >100 kHz PWM in servo drives and PFC stages |
| Pb-Free & Safety Certified | RoHS-compliant construction with UL E72422, CSA CA101391, SEMKO EN 60950, and optional VDE 0884-5 approval |
| DIP Package | Standard through-hole footprint enables manual rework, thermal relief design, and compatibility with legacy manufacturing lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar IGBT gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP350(F)-TP | Lower peak output (1.5 A), slower tPLH/tPHL (500 ns), no UVLO hysteresis | Suitable for lower-power (<5 kW) inverters with relaxed noise immunity requirements | Select when cost sensitivity outweighs need for 2.5 A drive strength and ±50 kV/μs CMR |
| ACPL-332J-500E | Higher speed (tPLH/tPHL = 100 ns), integrated Miller clamp, but only 2.0 A peak output | Better suited for SiC MOSFETs requiring active Miller clamping and tighter timing control | Choose when driving wide-bandgap devices where Miller-induced false turn-on is a primary concern |
Compared with TLP350(F)-TP and ACPL-332J-500E, PS9531-V-AX uniquely balances 2.5 A peak drive, ±50 kV/μs CMR, and UVLO hysteresis in a standard DIP package - making it optimal for ruggedized industrial IGBT drivers where reliability under harsh transients is non-negotiable.

FAQ
What is the maximum recommended forward current for the PS9531-V-AX LED input?
The PS9531-V-AX LED input has a recommended forward current of 8–12 mA per the datasheet's Recommended Operating Conditions. Absolute maximum forward current is 25 mA, but sustained operation above 12 mA reduces lifetime and increases thermal stress. For reliable switching, maintain IF = 10 mA with ≤0.5 μs rise/fall time to avoid input overdrive and ensure consistent threshold behavior across temperature.
Does PS9531-V-AX include built-in Miller clamping?
No, PS9531-V-AX does not include integrated Miller clamping. It provides a push-pull output stage capable of sourcing and sinking up to 2.5 A peak, but external Miller clamp circuitry (e.g., diode + resistor from VO to VEE) must be added when driving high-dv/dt SiC or GaN devices to prevent false turn-on. The device relies on fast fall time (≤40 ns) and high CMTI to mitigate Miller effects in IGBT applications.
Can PS9531-V-AX drive both N-channel and P-channel IGBTs?
PS9531-V-AX is configured as a low-side gate driver with VO referenced to VEE (output emitter). It directly drives N-channel IGBTs in common-emitter configuration. To drive P-channel IGBTs, external level-shifting or complementary driver pairing is required - the PS9531-V-AX itself does not support high-side floating bias or negative gate drive without auxiliary circuitry.
What safety certifications apply to PS9531-V-AX?
PS9531-V-AX carries UL recognition (E72422), CSA approval (CA101391), and SEMKO certification (EN 60950, EN 60065). Optional VDE 0884-5 (DIN EN 60747-5-5) certification is available for enhanced reinforced insulation validation. These approvals confirm its suitability for industrial equipment requiring double/reinforced insulation per IEC 61800-5-1 and IEC 62109.
How should unused pins (1, 4, 7) be handled in PCB layout for PS9531-V-AX?
Pins 1, 4, and 7 are NC (non-connected) terminals. Per the datasheet, they may be left unconnected or tied to GND on their respective sides (pins 1/4 to input GND; pin 7 to VEE or VO on output side). They must never be used for signal routing, bypassing, or thermal conduction - doing so degrades internal noise immunity and may compromise isolation integrity.
