Power management IC (PMIC) gate drivers constitute a vital part of power management in integrated circuits and devices. A gate driver is responsible for providing a high current drive to quickly turn on and off transistors, also known as gates, in applications such as motor control, automotive, communications and consumer electronics. The main purpose of a gate driver is to provide an accurate, reliable and timely signal to the gates of a power MOSFET or IGBT, to ensure optimum performance of the circuit.

The ISL89163FRTAZ-T is a high performance and low cost 6-bit gate driver IC designed to drive high load gates with a two-level supply voltage and output drive current up to 200mA. It features an integrated under-voltage lockout circuit to prevent false triggering, as well as a temperature-compensated reference voltage for accurate output. The ISL89163FRTAZ-T has a low on-resistance, which enables fast switching and low power dissipation. The chip is assembled in SO-16 package size that is suitable for automated assembly.

The ISL89163FRTAZ-T is designed for applications that require high speed and low power dissipation such as LCD displays, motor drivers, and automotive, communications and consumer electronics. It is suitable for use in applications where the operating voltage is in between 5 V and 24 V and output current is up to 200mA. The device is resistant to over-voltage, under-voltage, over-temperature and short-circuit conditions, making it suitable for harsh conditions.

The device operates via its static control logic, which consists of two control channels, one for each gate. The static control logic inputs correspond to the 6 outputs. Each of the 6 outputs contains two NMOS transistors, one for each gate. The external supply voltage applied to the chip is connected to the drain-source junction of these transistors to supply the required signal strength. The common gate of the two transistors is connected to the signal line.

The working principle of the ISL89163FRTAZ-T is very simple. The static control logic inputs act as the enable or disable signals for the two output gates. By applying a high or low signal to the static control logic inputs, the device will turn on or off its respective outputs. The high switching frequency of the device enables it to provide high speed operations.

As a high performance and low cost 6-bit gate driver IC, the ISL89163FRTAZ-T is a great option for a wide range of applications such as LCD displays, motor drivers and automotive, communications and consumer electronics. The high switching frequency and low on-resistance make it suitable for high speed operations, while the integrated under-voltage lockout circuit and temperature-compensated reference voltage provide an accurate and reliable output. Furthermore, the chip is easy to assemble in a small package size and is resistant to harsh conditions.
