Diodes Incorporated's 7-channel DMOS transistor array drives inductive loads while consuming minimal power

[July 28, 2022, Plano, Texas, USA] Diodes Incorporated (Diodes) has launched a new transistor array product. The ULN62003A consists of 7 500mA rated open-drain transistors, all of which are connected to the same ground pin. This high-current transistor array can drive a variety of loads, such as solenoids, relays, DC motors, and LED displays, and is mainly designed for climate control and home appliances. This product can be used in washing machines, dryers, microwave ovens, and air conditioning units.

The ULN62003A is built with DMOSFET output transistors, which have an output voltage drop of only 0.2V. This is much lower than pin-compatible bipolar devices. The resulting reduction in power consumption not only minimizes the overall power consumption of the application, but also alleviates heat-related issues and improves reliability. It can also control more devices while still maintaining the required die temperature.

The device also supports input voltages as low as -1V, providing greater flexibility by allowing the GND pin to be used to detect overcurrent conditions. This capability further improves system robustness and expands the product applications that the ULN62003A can address. Each output of the transistor array has clamping diodes to provide protection and improve reliability when driving inductive loads.

The ULN62003A is available in an SO-16 package and provides superior performance for many popular peripheral device drivers.

Precautions for using stm32 official SD card driver

Friends who use the SD card driver provided by the stm32 CUBE library should note: 1. Applicable to MMC cards. I haven't tested it. MMC cards are now collectibles. Who would still use them? So, ST team, please be rigorous. 2. The SD card initialization failed because after sending CMD0, CMD1 was sent (CMD1 is a unique
