Product details
Overview
R2A25110KSP from Renesas Electronics is an intelligent power device for IGBT gate drive with integrated micro isolator, designed for high-voltage inverter systems. It provides isolated gate drive (2500 VRMS), active Miller clamp, soft turn-off, dual-channel emitter current sensing (0.25 V typ. OC threshold), and dual IGBT temperature monitoring - enabling robust protection in automotive EV/HEV main inverters.
For engineers reviewing the R2A25110KSP datasheet, R2A25110KSP pinout, R2A25110KSP application, or R2A25110KSP equivalent, this page delivers verified technical context, confirmed isolation specs, validated fault-handling behavior, and real-world design implications for IGBT parallel driving and thermal safety-critical systems.
Technical Context
The R2A25110KSP implements a coreless transformer-based micro isolator delivering 2500 VRMS isolation and >35 kV/μs common-mode rejection between MCU-side (primary) and IGBT-side (secondary) circuits. Its dual-domain architecture separates VCC1 (5 V MCU supply) and VCC2/PVCC2 (15 V IGBT-side supplies), with independent GND2/PGND2 references.
It integrates two independent gate drive outputs (OUTH and OUTL), each with ≤1.0 Ω output resistance, supporting parallel IGBT configurations. Protection logic includes dual-channel CS inputs for overcurrent detection, dual TEMP inputs with PWM-encoded thermal feedback via TEMPOUT, and configurable fault hold timing via FHT1 capacitor.

Pinout & Package
Package: SSOP48 (0.5 mm pitch, 10.8 × 12.8 mm body size), thermally enhanced for high-power IGBT drive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA / INB | Primary-side gate input | Non-inverted (INA) and inverted (INB) logic inputs - support flexible MCU interface with internal PU/PD biasing |
| FO / FO_B | Primary-side fault output | Complementary fault signals (H-active / L-active) - enable direct MCU interrupt or latch logic without level translation |

Key Features
| Feature | Design Value |
|---|---|
| Micro Isolator with Coreless Transformer | 2500 VRMS isolation + >35 kV/μs CMR - eliminates optocoupler latency and aging while maintaining galvanic separation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar intelligent IGBT gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si827x series (Silicon Labs) | Capacitive isolation only; no integrated soft turn-off or temperature sensing; requires external protection ICs | Lacks on-chip IGBT protection logic - suitable for simpler systems where MCU handles fault decisions | Choose when isolation + basic gate drive suffices and protection is implemented externally |
| UCC21520 (Texas Instruments) | Reinforced isolation (5 kVRMS); dual-channel; no integrated current/temp sensing or soft turn-off | Requires external comparators, shunts, and thermal sensors - increases component count and layout complexity | Prefer for high-isolation-demand applications where full integration is not required |
Compared with Si827x and UCC21520, the R2A25110KSP uniquely combines micro-isolation, dual-channel protection sensing, and hardware-enforced soft turn-off in one SSOP48 package - reducing system-level design effort for automotive-grade IGBT inverters.

FAQ
What is the isolation rating and structure used in the R2A25110KSP?
The R2A25110KSP uses a coreless transformer-based micro isolator with 2500 VRMS isolation (60 sec) and >35 kV/μs common-mode rejection. This structure eliminates LED degradation and timing drift found in optocouplers, providing stable, high-speed signal transfer between MCU and IGBT domains. The R2A25110KSP achieves galvanic separation without optical components, enhancing long-term reliability in automotive applications.
How does the R2A25110KSP implement soft turn-off, and what external components are required?
The R2A25110KSP implements soft turn-off by driving the SOFT pin to discharge the IGBT gate gradually during fault conditions. An external resistor (RSOFT) must be connected between the SOFT pin and the IGBT gate to set the discharge rate and limit peak current. This prevents destructive voltage overshoot during abrupt shutdown. The R2A25110KSP's internal logic triggers SOFT automatically upon overcurrent, overtemperature, or UVLO detection - no MCU intervention needed.
Can the R2A25110KSP drive multiple IGBTs in parallel, and how is gate drive matching ensured?
Yes, the R2A25110KSP supports parallel IGBT driving via its ≤1.0 Ω gate drive output resistance on both OUTH and OUTL pins. Matching is ensured by identical internal drive strength and separate high-/low-side outputs, allowing symmetric external gate resistors (RGH/RGL). The R2A25110KSP also provides dual CS1/CS2 and TEMP1/TEMP2 inputs to monitor each IGBT individually - critical for balanced current sharing and thermal derating in parallel configurations.
What are the fault signaling mechanisms of the R2A25110KSP, and how is fault hold time configured?
The R2A25110KSP provides complementary fault outputs FO (active-high) and FO_B (active-low) on the MCU side, plus adjustable hold time via an external capacitor on the FHT1 pin. Faults include overcurrent, IGBT overtemperature, UVLO, timeout, and TSD. The R2A25110KSP holds the fault signal for a duration determined by CFHT1 (minimum 100 μs), ensuring MCU firmware has sufficient time to respond before automatic reset.
Does the R2A25110KSP include an on-chip voltage regulator, and what is its purpose?
Yes, the R2A25110KSP integrates a 5 V regulator outputting up to 5 mA from the VREG pin. It powers external circuitry such as temperature reference resistors (RTREF) and stabilizes internal bias networks. A 0.022 μF capacitor is mandatory on VREG for stability. The R2A25110KSP's VREG also feeds the SEL pin logic and TEMPVL threshold setting - making it essential for full protection functionality.
