DS1050U-005+T

Overview

The DS1050U-005+T is a 5-bit programmable pulse-width modulator (PWM) manufactured by Analog Devices/Maxim Integrated. It operates on a single 2.7V to 5.5V supply and features a standard frequency of 5kHz. The device utilizes a 2-wire addressable serial interface for control, allowing duty cycle adjustment from 0% to 96.88% in 3.125% steps, with an additional command for 100% duty cycle. It supports shutdown mode with standby current below 1µA. The component is housed in an 8-pin 118-mil µSOP package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

5-bit PWM resolution with adjustable duty cycle from 0% to 100%
Standard output frequency of 5kHz
2-wire addressable serial interface compatible with standard and fast modes
Low power consumption: 50µA active current and <1µA standby current

Applications

LCD contrast and brightness control
Power supply voltage adjustment
Battery charging or current adjustment

Procurement Notes

Verify the specific ordering suffix '+T' indicates tape and reel packaging if required by assembly equipment. Confirm the 'U' suffix corresponds to the 8-pin 118-mil µSOP package variant. Ensure the '-005' designation matches the required 5kHz frequency specification for the target design.

Selection Notes

Select this part when a fixed 5kHz PWM frequency is required. The 5-bit resolution provides 32 discrete duty cycle levels. Verify that the system can accommodate the ±20% output frequency tolerance across the specified temperature range. Ensure the microcontroller master supports the 2-wire protocol timing requirements for standard or fast mode operation.

Part Context

The DS1050 series includes variants with frequencies of 1kHz, 10kHz, and 25kHz. The 'U' suffix denotes the space-saving 8-pin µSOP package, while 'Z' denotes the 8-pin SOIC. The '005' suffix specifically sets the internal oscillator to 5kHz. This component belongs to the Dallas Semiconductor/Maxim Integrated line of digital potentiometers and programmable devices.
