Dallas Semiconductor DS1052 Datasheet
The DS1052 is a 5‑bit programmable pulse‑width modulator that provides an adjustable duty cycle from 0 % to 100 % and a fixed 100 kHz output frequency. It features a 2‑wire addressable serial interface, allowing up to eight devices to share the same bus, and is offered in 8‑pin SOIC and 8‑pin pSOP packages.
The device operates from a supply voltage of 2.7 V to 5.5 V and an ambient temperature range of –40 °C to +85 °C. Typical operating current is 100 µA, with a shutdown current of 1 nA. Electrical characteristics include a PWM output that swings from 0 V to VCC, 5‑bit resolution, and standard/fast‑mode I²C‑compatible timing parameters.
