ISL43L210IHZ-T application field and working principle

The ISL43L210IHZ-T is a device for the interface-analog switches, multiplexers, demultiplexers category. It is a high performance, dual SPDT low on resistance (<0.2 Ohms at VDD = 5V, VDI = 0.6V) analog switch that is manufactured using Intersil\'s submicron CMOS process. It is characterized within a wide supply range of 2.7V to 5.5V and can switch signals in the frequency range up to 25MHz.

The primary benefit of the ISL43L210IHZ-T device is its low on resistance to reduce power loss and eliminate temperature variances. This device is designed to replace mechanical analog switches and DIP switches with a single, RoHS-compliant switch. With its low on resistance, it will limit power losses, reducing power consumption and board temperature, as well as improving system reliability.

The ISL43L210IHZ-T consists of two sets of independently controlled single-pole, double-throw (SPDT) switches. It features a configurable power-up state, which allows the user to select either power-down or normal output operation on power up. It also has a standby pin that allows the user to place the device in a three-state condition.

The working principle of this device is based on the n-channel MOSFET technology. This device utilizes n-channel MOSFETs with a P-channel pull-up force in the switch channel. The switching of the switch is controlled by the low-voltage control pathways and logic. The MOSFET gates are driven by the logic inputs, which control whether the MOSFET is turned on or off, thus controlling the impedance of the switch.

The ISL43L210IHZ-T is suitable for applications such as sample and hold circuits, current sensing, temperature sensing, and switching for audio, video, optical, RF, motor control, and power management designs.
