DS1050 - 5-bit, programmable, PWM - 1kHz, 5kHz, 10kHz, and 25kHz
The DS1050 is a programmable, 5-bit, PWM with a 2-wire addressable control interface. The DS1050 operates from a power supply ranging from 2.7V to 5.5V. The PWM output provides a signal that fluctuates from 0V to VCC. The DS1050 requires a typical operating current of 50 A and a programmable shutdown supply current of 1 A at four standard PWM output frequencies, and offers four standard PWM output frequencies including 1kHz, 5kHz, and 10kHz and 25kHz. 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. This device is ideal for low cost LCD contrast and/or brightness control, supply voltage adjustment, and battery charging current regulation. The DS1050 is available in standard integrated circuit packages, an 8-pin (150 mil) SOIC and a space-saving 8-pin (118 mil) specialty clinic.
