DS1052X-100

5-Bit, Programmable, 100kHz Pulse-Width Modulator

2-Wire Interface Gives Processor Control of PWM Functions


Please check latest availability status for a specific part variant.

Description

The DS1052 is a programmable, 5-bit, pulse-width modulator featuring a 2-wire addressable controlled interface. The DS1052 operates from power supplies ranging from 2.7V up to 5.5V. The PWM output provides a signal that swings from 0V to VCC. The DS1052-100 requires a typical operating current of 100µA and a programmable shutdown supply current of 1µA. One standard PWM output frequency is offered: 100kHz. The 2-wire addressable interface allows operation of multiple devices on a single 2-wire bus and provides compatibility with other Dallas Semiconductor 2-wire devices such as real-time clocks (RTCs), digital thermometers, and digital potentiometers. The device is ideal for low-cost LCD contrast and/or brightness control, power supply voltage adjustment, and battery charging or current adjustment. The DS1052 is offered in standard integrated circuit packaging, including the 8-pin (150-mil) SOIC and space-saving 8-pin (118-mil) µSOP.
