The DS1052 is a programmable 5-bit pulse-width modulator with adjustable duty cycle, operating voltage range of 2.7V to 5.5V, standard frequency value of 100kHz, and a 2-wire addressable interface.
The DS1052 is a single‑chip, 5‑bit programmable pulse‑width modulator that operates from 2.7 V to 5.5 V. It provides a 100 kHz PWM output whose duty cycle can be set from 0 % to 96.88 % (full‑on command gives 100 %).
Communication is handled via a 2‑wire addressable serial interface compatible with other Dallas Semiconductor devices. Up to eight devices can share the bus, each selected by three address pins (A2, A1, A0). The datasheet includes electrical characteristics, absolute maximum ratings, and typical operating curves.
