Working Principle

The ISL6614CBZR5238 is designed to handle high-current and high-voltage applications. The gate driver has two outputs – high-side (HOUT) and low-side (LOUT) – which are designed to interface with the gate and drain of a power device such as a power MOSFET or an IGBT. The inputs include high-side and low-side enable signals (EN_H, EN_L), as well as a low-side bias voltage VB (which is adjustable). When the enable signals (EN_H, EN_L) are enabled, the ISL6614CBZR5238 drives the high-side output (HOUT) to the supply voltage and the low-side output (LOUT) to ground. This effectively turns on the power device, allowing current to flow from drain to source. The ISL6614CBZR5238 is designed to have a fast response time. The high-side output (HOUT) has a rise time of typically less than 140 nanoseconds and the low-side output (LOUT) has a rise time of typically less than 50 nanoseconds. This ensures improved operation of the power device and improved system efficiency.
