The SI8232AB-B-ISR isolator is a high-performance, single-channel non-inverting gate drive IC used in many applications where safety is essential, such as high voltage gas systems, LED lighting, power semiconductor motor control, temperature control, and more. This IC provides an isolation barrier between the gate driver and the low-voltage logic controller. This prevents any potential interference or noise from reaching the controller, since the isolation ensures that the voltage between the gate and logic is always observed correctly. The SI8232AB-B-ISR offer superior performance and isolation features, making them a popular option for many applications.

The SI8232AB-B-ISR isolator is a high-frequency device, as it operates up to 500kHz, easily exceeding most other gate drive ICs. It also features a normal quiescent current of 15mA, and a low whole operating current of only 20mA. This makes it suitable for use in multiple applications that require small amounts of power, such as automotive and industrial systems. Additionally, the operating temperature range of the SI8232AB-B-ISR is -40°C to +85°C, making it reliable for use in applications involving extreme temperatures.

The SI8232AB-B-ISR isolator offers excellent gate drive capability, leading to increased performance in all systems it is utilized in. It offers up to 8A current driving capability and a turn-on/turn-off time of 240ns/340ns. This allows for quick switching of the output with minimal power loss. The IC’s wide input voltage range of 4.5V - 15V ensures it is compatible with most standard CPU and logic controllers. The I/O isolation level of 2500Vrms is also highly impressive, further ensuring the safety integrity of the entire system.

The SI8232AB-B-ISR isolator is designed with a unique three-stage logic-LDO control architecture, which offers fast response times and high efficiency. This architecture also allows for features such as short-circuit current protection and thermal shut-off, ensuring the IC’s safety in extreme conditions. The thermal monitor, over-voltage monitor, and under-voltage monitor built into the IC also ensure it is always running in an optimal state. Additionally, the IC also offers various protections, such as against input voltage exceeding 25V, reverse battery, and over-current protection. This helps to keep the entire system running smoothly and safely in both normal and extreme operation conditions.

The SI8232AB-B-ISR isolator is an excellent choice for applications in which safety is essential, thanks to its impressive gate drive capability and impressive isolation features. The device offers excellent performance in all its applications, with a wide input voltage range, high switching frequency, and various protections. It is also an excellent choice for use in applications that require small amounts of power, due to its low quiescent and operating currents. Thanks to these features, the SI8232AB-B-ISR isolator is the perfect choice for many applications requiring isolation.
