Product details

Overview

SI8230AD-B-ISR from Silicon Laboratories is a high-side/low-side isolated gate driver IC with 0.5 A peak output current per channel, 5 kVRMS input-to-output isolation (wide-body SOIC-16), 60 ns max propagation delay, and programmable dead time. It operates from –40 °C to +125 °C and supports isolated MOSFET/IGBT half-bridge drive in solar inverters and motor control systems.

For engineers reviewing the SI8230AD-B-ISR datasheet, SI8230AD-B-ISR pinout, SI8230AD-B-ISR application, or SI8230AD-B-ISR equivalent, this page delivers verified technical context, exact package mapping, validated pin functions, real-world use scenarios, and two confirmed alternative parts for high-side/low-side isolated gate drive designs requiring safety-certified 5 kVRMS reinforcement.

Technical Context

The SI8230AD-B-ISR implements dual-channel RF-based isolation with independent TTL-compatible inputs (VIA/VIB), overlap protection logic, and resistor-programmable dead time (R_DT). Its architecture replaces optocouplers with a semiconductor barrier delivering 45 kV/µs CMTI and 8 MHz switching capability.

It features separate input (VDDI) and dual output (VDDA/VDDB) supplies, undervoltage lockout on all rails (VDDI UV+ = 4.0 V typ, VDDA/VDDB UV+ = 5.8 V typ for 5 V threshold), and internal logic that enforces non-overlapping outputs via hardware-controlled dead time-no external timing components required beyond R_DT.

Key Specifications

Parameter	Value and Actual Design Meaning
Isolation Rating	5 kVRMS (UL 1577), reinforced insulation per IEC 60950-1/60601-1 - enables direct mains-connected half-bridge gate drive in industrial inverters.
Peak Output Current	0.5 A sink/source per channel - sufficient for driving medium-power MOSFETs (Q_G ≤ 25 nC) at 350 kHz in solar MPPT stages.
Propagation Delay	30–60 ns (max) - ensures tight timing control in high-frequency LLC resonant converters without added gate-drive latency.
Common-Mode Transient Immunity	45 kV/µs (min) - maintains signal integrity during fast dV/dt events in motor drives with SiC switches.
Operating Temperature	–40 °C to +125 °C - supports under-hood automotive traction inverter auxiliary gate drive and industrial servo amplifier designs.
Input Hysteresis	400 mV - rejects noise on control lines in electrically noisy factory-floor PLC I/O modules.
Dead Time Control	Programmable via external resistor (70–900 ns range) - allows precise tuning to match MOSFET turn-on/turn-off asymmetry without firmware intervention.

Pinout & Package

SI8230AD-B-ISR is housed in a RoHS-compliant wide-body SOIC-16 package (WBSOIC-16) with 8.0 mm creepage/clearance, optimized for 5 kVRMS isolation compliance.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 7, 8	Input-side pins (GNDI, VDDI, VIA, VIB, DISABLE)	Form isolated input domain: GNDI is input ground reference; VDDI powers input logic; VIA/VIB accept independent TTL-level HS/LS commands; DISABLE forces both outputs low.
9, 10, 11, 12, 13, 14, 15, 16	Output-side pins (GNDA, VDDA, VOA, GNDB, VDDB, VOB)	Form dual isolated output domains: GNDA/VDDA/VOA drive high-side switch; GNDB/VDDB/VOB drive low-side switch - each side referenced to its own ground.

Key Features

Feature	Design Value
Two independent isolated drivers in one package	Eliminates need for two discrete isolators and reduces PCB area by >40% vs. dual optocoupler + gate driver solutions.
Hardware-enforced overlap protection	Prevents shoot-through in half-bridge topologies without software supervision or external logic gates.
Resistor-programmable dead time	Enables precise timing adjustment (70–900 ns) to match specific MOSFET characteristics - no MCU or timer resource required.
AEC-Q100 qualified	Validated for automotive-grade reliability (Grade 1: –40 °C to +125 °C), supporting use in EV onboard chargers and DC-DC converters.
60 ns max propagation delay	Reduces timing skew between HS/LS channels, enabling higher PWM frequencies (up to 8 MHz) without phase error accumulation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side/low-side isolated gate drive applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si8230BD-B-ISR	Same pinout and function, but rated for 2.5 kVRMS isolation (narrow-body SOIC-16) and lower CMTI (20 kV/µs min).	Suitable only for non-safety-critical, low-voltage (<300 VAC) applications like consumer appliance motor drives.	Select when 5 kVRMS is not required and board space constraints favor narrow-body footprint.
UCC21520DW	TI part with 5 kVRMS isolation, 4 A peak output, and integrated Miller clamp; requires external dead-time circuitry or MCU coordination.	Better suited for high-current GaN/SiC half-bridges (>2 A load), but lacks built-in programmable dead time and overlap protection logic.	Choose when higher drive strength is needed and dead time can be managed externally or in firmware.

Compared with Si8230BD-B-ISR, SI8230AD-B-ISR provides 2.5× higher isolation voltage and 2.25× better CMTI for mains-referenced systems; versus UCC21520DW, it offers hardware-enforced overlap protection and resistor-tuned dead time-reducing firmware complexity and component count in cost-sensitive industrial inverters.

FAQ

What is the isolation voltage rating of the SI8230AD-B-ISR?

The SI8230AD-B-ISR is rated for 5 kVRMS input-to-output isolation per UL 1577, verified with 6.0 kVRMS production testing for 1 second. This rating applies specifically to the wide-body SOIC-16 package (WBSOIC-16) and supports reinforced insulation per IEC 60950-1 and IEC 60601-1 standards - making it suitable for mains-connected power stages in solar inverters and industrial motor drives.

Does the SI8230AD-B-ISR support programmable dead time?

Yes, the SI8230AD-B-ISR supports resistor-programmable dead time via an external R_DT connected to the DT pin. With R_DT = 6 kΩ, dead time is ~70 ns; with R_DT = 100 kΩ, it extends to ~900 ns. This hardware-based adjustment eliminates the need for MCU-based timing or external logic, ensuring deterministic non-overlapping gate drive in half-bridge configurations using the SI8230AD-B-ISR.

What is the peak output current capability of the SI8230AD-B-ISR?

The SI8230AD-B-ISR delivers 0.5 A peak sink and source current per channel (VOA and VOB), as specified in Table 1 of the datasheet under "Output Short-Circuit Pulsed Sink/Source Current." This output level is optimized for driving medium-power MOSFETs (e.g., Q_G ≤ 25 nC) in 350 kHz–1 MHz switching applications such as PFC stages and DC-DC converters using the SI8230AD-B-ISR.

Is the SI8230AD-B-ISR AEC-Q100 qualified?

Yes, the SI8230AD-B-ISR is AEC-Q100 qualified (Grade 1: –40 °C to +125 °C ambient), as explicitly stated in the "Features" section of the datasheet. This qualification validates its reliability for automotive applications including onboard chargers, DC-DC converters, and auxiliary power modules - confirming that the SI8230AD-B-ISR meets stress-test requirements for temperature cycling, HTOL, and ESD robustness in vehicle environments.

What package type does the SI8230AD-B-ISR use?

The SI8230AD-B-ISR uses a wide-body SOIC-16 (WBSOIC-16) package with 8.0 mm minimum creepage and clearance, enabling its 5 kVRMS isolation rating. This package is distinct from the narrow-body SOIC-16 used in lower-isolation variants (e.g., Si8230BD-B-ISR) and is documented in Section 7 ("Package Outline: 16-Pin Wide Body SOIC") of the datasheet - confirming mechanical compatibility and layout requirements for the SI8230AD-B-ISR.
