DS1052U-100

Overview

The DS1052U-100 is a programmable, 5-bit pulse-width modulator (PWM) manufactured by Analog Devices Inc./Maxim Integrated. It operates from power supplies ranging from 2.7V to 5.5V and features a standard frequency value of 100kHz. The device provides an adjustable duty cycle from 0% to 100%, with the PWM output swinging from 0V to VCC. Typical operating current is 100µA, while shutdown supply current is programmable to 1µA. It utilizes a 2-wire addressable controlled interface and is housed in an 8-pin uSOP package, suitable for operation between -40°C and +85°C.

Feature Summary

• Single 5-bit programmable pulse-width modulator with adjustable duty cycle from 0% to 100%
• Operates on a single power supply ranging from 2.7V to 5.5V
• Standard frequency value of 100kHz with typical operating current of 100µA
• Features a 2-wire addressable controlled interface for communication

Applications

• Battery-powered systems requiring low power consumption
• LCD bias voltage generation
• LED backlight control
• Motor speed control applications

Procurement Notes

Verify the specific suffix 'U' indicates the 8-pin uSOP package variant when sourcing. Confirm the '-100' designation corresponds to the 100kHz standard frequency setting. Check manufacturer documentation for any obsolescence notices or lifecycle status updates prior to finalizing procurement plans.

Selection Notes

Select this component when a precise 5-bit resolution PWM signal is required within a 2.7V to 5.5V supply range. Ensure the design accommodates the 2-wire addressable interface protocol. Compare against the DS1050 series if different standard frequencies (1kHz, 5kHz, 10kHz, 25kHz) are needed instead of the 100kHz option provided by the DS1052.

Part Context

The DS1052 belongs to the Maxim Integrated family of programmable pulse-width modulators. It shares architectural similarities with the DS1050 but offers a higher standard frequency of 100kHz compared to the lower frequency options available in the DS1050 series. Both devices utilize a 2-wire interface and are designed for low-power applications.

Replacement Considerations

The DS1050U-100+ is a related part within the same product family but typically supports different standard frequencies such as 1kHz, 5kHz, 10kHz, or 25kHz. Verify that the 100kHz frequency specification of the DS1052 is compatible with the target application before substituting with other members of the DS105x series.
