DS1050U-005 5kHz 8-Pin 118-mil mSOP DS1050U-010 10kHz DS1050U-025 25kHz 8-Pin 118-mil µSOP DESCRIPTION The DS1050 is a programmable, 5-bit, pulse-width modulator featuring a 2-wire addressable controlled interface. The DS1050 operates from power supplies ranging from 2. 5.5V. The PWM output provides a signal that swings from and a programmable shutdown supply current of 1mA ...

OPERATION Interface protocol is simplified to an 8-bit control byte and 8-bit data byte. Information can be read or written to the DS1050 including a commanded shutdown operation. Power-Up Configuration The DS1050 powers-up to half-scale (10000B) providing 50% duty-cycle. In ...

The following bus protocol has been defined (see Figure 2). § Data transfer may be initiated only when the bus is not busy. § During data transfer, the data line must remain stable whenever the clock line is HIGH. Changes ...

The master device generates all serial clock pulses and the START and STOP conditions. A transfer is ended with a STOP condition or with a repeated START condition. Since a repeated START condition is also the beginning of the next ...

The command operation “Set Shutdown Mode” is used to provide a low-current (inactive state) state for the DS1050. When in a low-current state the DS1050 will draw currents less than or equal to 1mA. The PWM output will be high ...
