Product details
Overview
SI8236BA-C-IMR from Silicon Laboratories is a 4.0 A peak dual isolated gate driver in a 16-pin wide-body SOIC package, featuring 5 kVRMS input-to-output isolation, 60 ns max propagation delay, and programmable dead time control. It drives two independent high-side or low-side MOSFET/IGBT gates in industrial inverters and motor control systems where reinforced insulation and fast switching are critical.
For engineers reviewing the SI8236BA-C-IMR datasheet, SI8236BA-C-IMR pinout, SI8236BA-C-IMR application, or SI8236BA-C-IMR equivalent, this page delivers verified electrical specs, safety-certified isolation parameters, thermal derating data, dual-channel timing behavior, and real-world design guidance for isolated half-bridge and dual-switch topologies.
Technical Context
The SI8236BA-C-IMR implements RF-based on/off keying across a silicon isolation barrier, enabling robust noise immunity without startup initialization. Its dual-channel architecture supports independent TTL-compatible inputs (VIA/VIB) with >400 mV hysteresis and operates with VDDI = 2.7–5.5 V and VDDA/VDDB = 6.5–24 V.
It integrates overlap protection and programmable dead time via external resistor (RDT), supporting 70–900 ns dead time ranges. Common-mode transient immunity exceeds 45 kV/µs at 1500 VCM, and it meets UL 1577 (5 kVRMS), VDE 0884-5, CSA 5A, and CQC GB4943.1 safety standards for reinforced insulation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8235BD-C-IMR | Same 4.0 A dual-driver family, but narrow-body SOIC-16 (2.5 kVRMS isolation) | Limited to lower working voltage systems (<600 VRMS reinforced insulation) | Select when board space is constrained and 2.5 kVRMS isolation suffices |
| UCC21520DW | Texas Instruments dual-channel isolated driver; 4 A sink/source, 5 kVRMS, but uses capacitive isolation and different UVLO thresholds | Requires separate enable/disable logic; no integrated overlap protection | Choose when TI ecosystem integration or specific EMI profile is prioritized over hardware overlap guard |

FAQ
What is the maximum isolation voltage rating for SI8236BA-C-IMR?
SI8236BA-C-IMR is rated for 5 kVRMS input-to-output isolation per UL 1577 (1 minute test), validated for reinforced insulation in systems up to 600 VRMS working voltage. This rating applies specifically to its wide-body SOIC-16 package, which achieves 8.0 mm creepage and clearance.
Does SI8236BA-C-IMR support programmable dead time, and how is it configured?
Yes, SI8236BA-C-IMR supports programmable dead time via an external resistor (RDT) connected between the DT pin and VDDI. With RDT values from 6 kΩ to 220 kΩ, dead time is adjustable from 70 ns to 900 ns. This feature is implemented in hardware and requires no firmware or configuration registers.
What safety certifications does SI8236BA-C-IMR hold?
SI8236BA-C-IMR holds UL 1577 (5 kVRMS), VDE 0884-5 (IEC 60747-5-5), CSA Component Notice 5A (IEC 60950-1/61010-1/60601-1), and CQC GB4943.1 certifications-all verified for its 5 kVRMS wide-body SOIC-16 variant. These cover reinforced insulation for industrial and medical applications.
Can SI8236BA-C-IMR drive both high-side and low-side switches in a half-bridge configuration?
Yes, SI8236BA-C-IMR can drive both high-side and low-side switches in a half-bridge, but it operates as a dual independent driver-not a dedicated high-side/low-side pair like Si8233/Si8234. Each channel (VOA/VOB) is fully isolated and configurable, enabling custom HS/LS sequencing with external logic or MCU control.
What is the common-mode transient immunity (CMTI) specification for SI8236BA-C-IMR?
SI8236BA-C-IMR guarantees ≥45 kV/µs common-mode transient immunity at VCM = 1500 V, measured per Figure 6 in the datasheet. This ensures reliable operation during fast dV/dt events typical in IGBT and SiC-based inverters, preventing false triggering or output glitches.
