Product details
Overview
SI82395CB-IS1R from Skyworks Solutions is a dual-channel isolated gate driver IC designed for high-side/low-side MOSFET and IGBT control in power converters. It delivers 4.0 A peak output current, operates with 2.5 V–5.5 V input supply (VDDI), supports up to 5 kVRMS isolation, and features enhanced UVLO with status feedback and 1 ms safe delayed startup. It is used in solar inverters and traction inverters requiring robust isolation and fault-aware gate drive.
For engineers reviewing the SI82395CB-IS1R datasheet, SI82395CB-IS1R pinout, SI82395CB-IS1R application, or SI82395CB-IS1R equivalent, key selection criteria include its 12 V output UVLO threshold, SOIC-16 narrow-body package, programmable dead time (10–200 ns), deglitch filtering, and AEC-Q100 qualification for automotive-grade variants.
Technical Context
The SI82395CB-IS1R implements RF-based silicon isolation with on/off keying modulation, enabling high CMTI (100 kV/µs) and low propagation delay (30 ns). Its architecture separates input logic (VIA/VIB) from two independent isolated driver outputs (VOA/VOB), each with dedicated VDDA/VDDB supplies and individual UVLO monitoring.
It supports independent dual-input operation (not PWM mode), includes an active-high EN pin for system-level safety shutdown, and provides RDY status feedback. The device defaults outputs low during VDDI power-down - a fail-safe behavior critical for motor control and inverter reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5 kVRMS withstand voltage - enables reinforced insulation per IEC62368-1 and UL 1577 for safety-critical power systems. |
| Peak Output Current | 4.0 A - sufficient to rapidly charge/discharge high-Qg MOSFETs and IGBTs in 10–100 kHz switching applications. |
| Input Supply Range | 2.5 V–5.5 V VDDI - compatible with modern low-voltage microcontrollers and FPGA I/O without level-shifting. |
| Output UVLO Threshold | 12 V - ensures gate drivers remain disabled until driver-side supplies stabilize above safe turn-on voltage. |
| Propagation Delay | 30 ns - minimizes timing skew between high-side and low-side channels, supporting tight dead-time control. |
| Operating Temperature | –40 °C to +125 °C - meets industrial and automotive under-hood thermal requirements without derating. |
| Package | SOIC-16 narrow body - RoHS-compliant, JEDEC-standard footprint with 260 °C reflow compatibility. |
Pinout & Package
SI82395CB-IS1R is housed in a 16-pin narrow-body SOIC package (7.5 mm × 10.3 mm, 1.27 mm pitch) with creepage/clearance optimized for reinforced isolation. Pin 1 is marked with a dot; pin numbering follows standard SOIC convention (counterclockwise from top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Channel A input | TTL-compatible high-true logic input controlling VOA; referenced to GNDI. |
| VIB | Channel B input | TTL-compatible high-true logic input controlling VOB; referenced to GNDI. |
| EN | Enable input | Active-high safety control: forces both outputs low when deasserted, independent of VIA/VIB state. |
| VDDI | Input-side supply | 2.5–5.5 V power for logic and isolation barrier; UVLO triggers if <1.9 V (typical). |
| GNDI | Input-side ground | Reference for VIA, VIB, EN, VDDI, and RDY; galvanically isolated from power-side grounds. |
| RDY | Ready status output | Open-drain digital flag indicating valid output operation after startup delay and UVLO exit. |
| VDDA | Driver A supply | 10–24 V supply for high-side or low-side output stage A; monitored for UVLO (12 V threshold). |
| VOA | Driver A output | 4 A capable push-pull output; driven low on VDDA UVLO or EN deassertion. |
| GND1 | Driver A ground | Power ground for VDDA/VOA path; isolated from GNDI and GND2. |
| VDDB | Driver B supply | 10–24 V supply for second output stage; independently monitored for UVLO (12 V threshold). |
| VOB | Driver B output | 4 A capable push-pull output; driven low on VDDB UVLO or EN deassertion. |
| GND2 | Driver B ground | Power ground for VDDB/VOB path; isolated from GNDI and GND1. |
| NC | No connect | Pins 13 and 14 are internally unused; must be left floating or tied to GND2 per layout guidelines. |
| NC | No connect | Pins 15 and 16 are internally unused; must be left floating or tied to GND2 per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Enhanced UVLO with status feedback | Monitors VDDA and VDDB independently at 12 V threshold and asserts RDY only when both are valid - prevents partial drive during supply sequencing. |
| Fail-safe default-low outputs | VOA and VOB automatically go low if VDDI is unpowered or EN is deasserted - eliminates shoot-through risk in power stages. |
| Programmable dead time | Configurable 10–200 ns internal delay between complementary outputs - simplifies timing margining without external RC networks. |
| Deglitch filtering | Internal noise rejection circuitry suppresses <50 ns transients on VIA/VIB - improves immunity in noisy motor drive environments. |
| AEC-Q100 qualified variant available | SI82395CB-AS1R shares identical electrical specs and pinout - enables drop-in qualification upgrade for automotive OBC and BMS designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI82335CB-IS1R | Same SOIC-16 NB package and 4 A drive, but lacks RDY pin and enhanced UVLO status feedback; UVLO is basic (no status pin). | Suitable for cost-sensitive industrial inverters where system-level ready signaling is handled externally. | Select when RDY handshake and independent UVLO status reporting are not required - reduces BOM count and firmware complexity. |
| UCC5390SCDR | TI part with 5 A drive, 3.3/5 V logic compatibility, and integrated Miller clamp; no programmable dead time or deglitch filter. | Better suited for high-speed SiC gate driving with active Miller clamping, but requires external UVLO supervision. | Prefer when driving >1000 V SiC devices with stringent Miller-induced turn-on prevention - not drop-in due to different pinout and enable logic. |
Compared with SI82335CB-IS1R and UCC5390SCDR, the SI82395CB-IS1R uniquely combines RDY status feedback, 12 V enhanced UVLO with independent monitoring, and programmable dead time in a single SOIC-16 NB package - making it optimal for automotive-grade inverter designs requiring functional safety awareness and deterministic startup behavior.

FAQ
What is the UVLO threshold for SI82395CB-IS1R driver supplies?
The SI82395CB-IS1R features enhanced UVLO with a fixed 12 V threshold on both VDDA and VDDB supplies. When either supply drops below this level, the corresponding output (VOA or VOB) is actively driven low, and the RDY pin is deasserted. This behavior is confirmed in Table 2.2 of the Si8239x datasheet and applies specifically to SI82395CB-IS1R as a member of the Si82395x subfamily.
Does SI82395CB-IS1R support PWM input mode?
No, SI82395CB-IS1R does not support PWM input mode. It is configured as an independent dual-input driver with separate VIA and VIB control lines. PWM-mode variants (e.g., SI82394x/8x) are distinct part numbers with different logic behavior and pin assignments. The SI82395CB-IS1R truth table in datasheet Table 2.2 confirms high-true independent control of VOA and VOB.
What is the meaning of "CB" in SI82395CB-IS1R?
In the SI82395CB-IS1R ordering code, "CB" denotes the output UVLO threshold setting: "C" = 12 V, "B" = enhanced UVLO with status feedback (RDY pin active). This coding is defined in Table 1.1 of the Si8239x datasheet and distinguishes SI82395CB-IS1R from variants like SI82395AB-IS1R (6 V UVLO) or SI82395BB-IS1R (8 V UVLO), all sharing the same SOIC-16 NB package and functional set.
Is SI82395CB-IS1R pin-compatible with automotive-grade SI82395CB-AS1R?
Yes, SI82395CB-IS1R and SI82395CB-AS1R are fully pin-compatible and functionally identical. Per datasheet Note 5, Automotive-Grade devices use the same construction materials, topside marking, and electrical parameters as Industrial-Grade versions - differing only in manufacturing flow (automotive-specific process controls) and documentation (PPAP, IMDS). No PCB or schematic changes are needed for qualification migration.
What isolation certifications apply to SI82395CB-IS1R?
SI82395CB-IS1R is rated for up to 5 kVRMS isolation and complies with UL 1577 (5000 Vrms/1 min), CSA, VDE 0884-10 (basic), and IEC62368-1/EN60950-1 (reinforced insulation) standards. These certifications are explicitly listed in the Safety Approvals section of the Si8239x datasheet and apply to all Si8239x variants including SI82395CB-IS1R.
