This document describes the features of CA158, CA158A, CA258, CA358, CA358A, and CA2904 types, which are dual channel, high gain, internally frequency compensated operational amplifiers. They can operate from a single power supply or split power supplies and are useful in interface circuits with digital systems, transducer amplifiers, and other conventional op amp circuits.

The ISL88031 is a five-voltage monitor with industry-leading reset threshold accuracy and low power consumption. The device provides a variety of common features such as power-on reset, undervoltage supply monitoring, reset signaling and manual reset. The ISL88031 uses a small 8-pin MSOP package to monitor up to 5 different voltage levels, which can help reduce system costs, reduce board space requirements and improve system reliability.

The ISL88021 and ISL88022 are customizable triple voltage-monitoring supervisors that assert a reset if any of the monitored voltages becomes non-compliant. They offer popular functions such as Power-On-Reset timing control with both RESET and RESET outputs, Supply Voltage Supervision, both under or overvoltage detection, and Manual Reset assertion. By offering these features in a small 8 Ld MSOP package, the ISL88021 and ISL88022 can lower system cost, reduce board space requirements and increase the reliability of systems.

ISL6208 is a high-frequency, dual MOSFET driver optimized to drive two N-Channel power MOSFETs in a synchronous-rectified buck converter topology. It is especially suited for mobile computing applications that require high efficiency and excellent thermal performance.

Each driver is capable of driving a 3000pF load with propagation delays of 8ns and transition times under 10ns. Bootstrapping is implemented with an internal Schottky diode. This reduces system cost and complexity, while allowing the use of higher performance MOSFETs.

The ISL6209 is a high frequency, dual MOSFET driver, optimized to drive two N-Channel power MOSFETs in a synchronous-rectified buck converter topology in mobile computing applications. This driver, combined with an Intersil Multi-Phase Buck PWM controller, such as ISL6216, ISL6244, and ISL6247, forms a complete single-stage core-voltage regulator solution for advanced mobile microprocessors. The ISL6209 features 4A typical sink current for the lower gate driver. The 4A typical sink current is capable of holding the lower MOSFET gate during the PHASE node rising edge to prevent the shoot-through power loss caused by the high dv/dt of the PHASE node.

The ISL6210 is a dual-power synchronous rectified MOSFET driver from Intersil. It is optimized to drive two independent power channels in a synchronous-rectified buck converter topology. The ISL6210 together with an Intersil ISL62xx multiphase PWM controller forms a complete single-stage core-voltage regulator solution with high efficiency performance at high switching frequency for advanced microprocessors. The IC is biased by a single low voltage supply (5V), minimizing driver switching losses in high MOSFET gate capacitance and high switching frequency applications. Each driver is capable of driving a 3nF load with less than 10ns rise/fall time. Bootstrapping of the upper gate driver is implemented via an internal low forward drop diode, reducing implementation cost, complexity, and allowing the use of higher performance, cost effective N-Channel MOSFETs. Adaptive shoot-through protection is integrated to prevent both MOSFETs from conducting simultaneously. The ISL6210 features 4A typical sink current for the lower gate driver, enhancing the lower MOSFET gate hold-down capability during PHASE node rising edge, preventing power loss caused by the self turn-on of the lower MOSFET due to the high dV/dt of the switching node.
