Application Scenarios & Design Considerations

DC/DC Converter IC for Charging

Alternative Part Number

  • DS1302 --: Real-time clock IC with similar serial interface and function, widely available and well documented.
  • PCF8563 --: Low-power real-time clock/calendar with I2C interface, a common functional substitute.
  • HT1381 --: Serial real-time clock chip with comparable pinout and timing functions, cost-effective alternative.
  • MAX3832E --: Similar part number family and function; Maxim offers comparable analog/mixed-signal ICs, but verify exact electrical specifications and pinout before substitution.
  • AD3832 --: Analog Devices provides functionally similar signal-conditioning ICs; check datasheet parameters such as supply voltage, bandwidth, and package compatibility.
  • LM3832 --: Texas Instruments offers a broad range of comparable analog ICs; confirm that key specifications and package match the original MB3832A requirements.
  • DS1338Z-33+ --: I2C real-time clock with integrated crystal and 3.3V operation, functionally similar to the MB3832A RTC and widely available.
  • PCF8563T --: Low-power I2C real-time clock/calendar in SO-8, a common drop-in style replacement for Fujitsu RTC devices with compatible bus interface.
  • RV-8564-C3 --: I2C real-time clock module with embedded crystal, offering similar timekeeping function and low power consumption as an alternative source.
