Description

DDA001AG is Power Supply IC Chip. A power supply IC chip, often referred to as a voltage regulator IC or voltage regulator, is a semiconductor device used to control and regulate the voltage supplied to electronic circuits and components. These chips are essential in various electronic devices and systems to ensure a stable and constant voltage supply.

Features

1. Linear Voltage Regulators: Linear voltage regulators are used to provide a stable output voltage from a variable or higher input voltage. They are straightforward and efficient but are best suited for low-to-moderate current applications.

2. Switching Voltage Regulators: Switching voltage regulators, also known as DC-DC converters, are more complex but highly efficient. They can step up (boost), step down (buck), or invert the input voltage to produce a regulated output voltage.

3. LDO (Low Dropout) Regulators: LDO regulators are a type of linear regulator that can maintain a stable output voltage even when the input voltage is only slightly higher than the desired output voltage. They are commonly used in battery-powered devices.

DS3231 – Precision Real-Time Clock IC

Part Number: DS3231, DS3231SN

Function: Extremely Accurate Real-time Clock (RTC) IC

Package: SO 16 Pin type

Manufacturer: Dallas, Maxim

ds3231-precision-rtc

Description

The DS3231 is a low-cost, extremely accurate I²C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, and maintains accurate timekeeping when main power to the device is interrupted. The integration of the crystal resonator enhances the long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line. The DS3231 is available in commercial and industrial temperature ranges, and is offered in a 16-pin, 300-mil SO package.

The RTC maintains seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with an active-low AM/PM indicator. Two programmable time-of-day alarms and a programmable square-wave output are provided. Address and data are transferred serially through an I²C bidirectional bus.
