Transistors offer overload delay
07.06.2018 · Circuits
Although an SMPS can protect itself against permanent short circuits, it sometimes has problems when dealing with transient overloads. Transient overloads are not short circuits but can push the power supply above its nominal load value. This scenario occurs with typical loads such as printer heads and small motors...
Maxim's Low-Power Microcontrollers Extend Battery Life for Wearables and Other Compact Devices
Designers of internet of things sensors, environmental sensors, smartwatches, medical/preventive health wearables, and other size-constrained devices can now increase battery life and functionality using the ultra-low power MAX32660 and MAX32652 microcontrollers from Maxim Integrated Products...
Achieve simple IR-data transmission from a PC's serial port
06.06.2018 · Circuits
Often, you need to transmit a couple of bits or bytes of data to a microcontroller without a direct cable connection. One simple way to achieve this goal is to use a widely available IR receiver, such as a TSOP17xx or similar receiver from Vishay that finds use in IR-remote-control applications...
Vishay Intertechnology Launches Its First Automotive Grade Phototransistor Optocoupler
06.06.2018 · News
Vishay Intertechnology launched its first Automotive Grade phototransistor optocoupler, the VOMA617A. The new device combines a high current transfer ratio with a low forward current of 5 mA in the compact SOP-4 mini-flat package...
Cascode MOSFET increases boost regulator's input- and output-voltage ranges
05.06.2018 · Circuits
Targeting use in portable-system applications that require raising a battery's voltage to a higher level, IC boost regulators often include output transistors that can drive storage inductors. However, most boost regulators' absolute-maximum input-voltage rating typically doesn't exceed 6 V, an adequate level for battery operation...
