Introduction

DS3164 is a specialized integrated circuit (IC) designed and manufactured by Microchip Technology. It is specifically designed for small, space limited applications like consumer electronics, small office/home office, and portable devices. The large amount of digital I/O available with the DS3164 makes it an excellent choice for applications requiring sensor monitoring and/or control.

Application Field

The DS3164 is most commonly used in applications requiring a miniature size, low power, and control applications. This includes wearable and mobile devices, medical diagnostic and wearable medical devices, small robotics, robotics enabling medical and industrial applications, automotive, HVAC, and more. The DS3164 is great for applications where size, cost and power are limited. It features a fully customizable, PWM-compatible, six-output, step-down DC/DC converter for reliable, efficient and cost-effective power supply. It also features rich analog and communication peripherals, such as an 8-channel analog-to-digital converter, 12-bit resolution timers, and an integrated I2C-compatible interface.

Working Principle

The DS3164 features a fully adjustable, step-down DC/DC converter that is optimized for size and power efficiency. Input voltage ranges from 2.7V to 5.5V. The buck converter outputs 5V, 3.3V, 1.8V and 1.2V, each with a maximum output current of 90mA. The buck converter is also equipped with OTP or external soft-start, over-voltage and under-voltage protection, clock frequency adjustment and Enable pins.

The DS3164 also contains several other useful features. It includes an 8-channel analog-to-digital converter that supports both single-ended and differential inputs with 12-bit resolution. Internal temperature sensing is also included for temperature monitoring and control. Additionally, the DS3164 has a host of communication peripherals, such as an I2C-compatible serial interface, SPI, SPI flash and UART.

The DS3164 also features a wide variety of interrupts and wake-up sources, a 32KB of SRAM, watch dog timers, real-time clock and several other features. The whole package is designed for advanced power management and easy system integration.
