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 100A and a programmable shutdown supply
current of 1A.
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)
mSOP.
