ISL90462WIH627-TK

Digital Potentiometers Overview

The ISL90462WIH627-TK is a single volatile digitally controlled potentiometer (XDCP) from Renesas, housed in a 6-lead SOT-23 package. It features a 10kΩ end-to-end resistance with 32 wiper tap points and operates on a supply voltage of 2.7V to 5.5V. The device utilizes a 2-pin Up/Down interface for control and includes volatile memory to retain settings only while powered. Key electrical specifications include a typical temperature coefficient of ±35ppm/°C, an active current of 25µA maximum, and a standby supply current of 0.3µA.

Digital Potentiometers Feature Summary

• Single-channel volatile solid-state potentiometer with 32 discrete wiper tap points
• Simple 2-pin serial interface using Chip Select (CS) and Up/Down (U/D) inputs
• Low power consumption with 25µA max active current and 0.3µA standby current
• Industrial temperature range operation from -40°C to +85°C

Digital Potentiometers Applications

• LCD contrast control circuits
• Parameter and bias adjustments in electronic systems
• Industrial and automotive control modules
• Transducer adjustment for pressure, temperature, position, chemical, and optical sensors
• Laser diode driver biasing and gain control

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'TK' against manufacturer documentation to confirm tape and reel packaging details. Confirm RoHS compliance status if lead-free requirements are mandatory for the assembly process. Check for End-of-Life notifications as this component was introduced by Intersil prior to its acquisition by Renesas.

Digital Potentiometers Selection Notes

Select this component when a compact, low-power digital solution is required for variable resistance applications. Ensure the system design accounts for volatile memory behavior, as the wiper position resets upon power loss. Verify that the 10kΩ resistance value aligns with the circuit's impedance requirements and that the 2-pin interface timing meets the controller's output capabilities.

Digital Potentiometers Part Context

This part belongs to the ISL9046X series of XDCPs, which were marketed as industry-leading small-footprint solutions. The 'W' designation indicates the 10kΩ resistance variant, while 'H' specifies the SOT-23 package. The device represents a transition period product originally released by Intersil before becoming part of the Renesas portfolio.

Digital Potentiometers Replacement Considerations

Direct replacements within the same family include ISL90462WIE627-TK for SC-70 packaging or ISL90462UIH627-TK for 50kΩ resistance. Cross-vendor equivalents require matching the 32-tap resolution, volatile memory type, and 2-pin control interface.
