The ISL6615AFRZ-T is a member of Intersil’s ProASIC3 family of Programmable Mixed-Signal ICs (PMICs). It is a versatile product, providing high integration and low power dissipation through advanced technology. The device includes an integrated half-bridge driver IC, which offers both a high current output for driving external MOSFETs and a low current output for controlling the gate of the MOSFET. It also provides two channels of independent gate drivers and a single-ended output driver.

Intersil’s ISL6615AFRZ-T supports a variety of applications, including power supplies, in-vehicle power distribution, white goods, communication infrastructure, and automotive electronics. It can also be used in various industrial control applications, as well as solar, UPS, and LED lighting applications. Furthermore, it is suitable for use in miniaturized power supplies, as it takes up less space in a circuit. Additionally, its quiescent current of less than 15 μA makes it energy efficient.

The ISL6615AFRZ-T has two independent gate driver channels with a single-ended output driver channel. It has a current capability up to 4A per channel, with a 4-bit dual-channel A/B binary output enabling it to drive both low-side and high-side MOSFETs. The device also provides a slew rate of 6ns or 12ns for a low side MOSFET drive, and 6ns or 12ns/2ns for a high side MOSFET drive. The output driver channel has a current capability up to 4A.

The ISL6615AFRZ-T carries a Group 4 Functional Safety Rating, and is designed to help protect against undershoot, short circuit and overtemperature situations. It features a built-in over-temperature protection (OTP), which trips if the device temperature exceeds 175°C. It also has an under-voltage lockout (UVLO) feature to protect components during startup and to avoid no switching conditions due to low voltages.

Furthermore, the device also features on-board protection against over-current and overshoot conditions, as well as built-in diagnostic monitoring to ensure proper operation of the connected gate drivers and prevent thermal run-away. Finally, the gate driver can be controlled using logic-level inputs or through a PWM signal.

In conclusion, the ISL6615AFRZ-T is a simple, highly integrated PMIC-Gate Driver featuring a half-bridge driver IC and single-ended output driver. It is suitable for use in power supplies, automotive electronics, industrial control applications, and LED lighting applications. It is also energy efficient and has a variety of built-in protection features to help ensure accurate, reliable operation.
