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 V_CC.

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) ꢀSOP.
