Is my power supply OK, and what if it isn’t? Is my microprocessor still working? In part 1, we examined the operation of power supply supervisory ICs that can detect when the supply voltage is too low, and what might happen if so. We will continue that analysis and then consider ways to keep an […]

Power-supply supervisors keep circuits in check: part 1
Is my power supply OK? What about my microprocessor? What if something goes wrong? Simulations show what happens if DC voltage drops. Microprocessors can behave in unwanted ways when their power supplies don’t deliver the expected voltage. Errors can occur, circuits can unexpectedly reset or even go rogue. To prevent such problems, many devices use […]
Automotive-grade 20 Gbps video switch targets infotainment and ADAS systems
Diodes Incorporated has introduced the PI3WVR14412Q, an automotive-compliant* 20Gbps 1:2 video switch for in-cabin infotainment and advanced driver assistance systems (ADAS) applications. This device features a space-saving design and is qualified for elevated temperatures. The switch has four high-speed lanes with a 10GHz bandwidth to handle DisplayPort 2.1, HDMI 2.1, MIPI DPHY/CPHY, USB 3.2, and […]
Eight SiC Schottky barrier diodes rated at 1200V
Diodes Incorporated announced the release of its first Silicon Carbide (SiC) Schottky barrier diodes (SBD). The portfolio includes the DIODES DSCxxA065 series with eleven products rated at 650V (4A, 6A, 8A, and 10A) and the DIODES DSCxx120 series with eight products rated at 1200V (2A, 5A, and 10A). These wide-bandgap SBDs bring the benefits of significantly […]
Precision op-amps offer wide dynamic range, low noise
Diodes Incorporated is addressing the need for advanced signal conditioning in modern automotive designs by introducing two precision operational amplifiers (op-amps) aimed at different signal frequency scenarios. The low signal-to-noise ratio characteristics of the DIODES AS2376Q mean it is optimized for high-frequency usages, such as in on-board chargers (OBCs), DC-DC converters, battery management system (BMS) […]

MOSFET half-bridge gate driver targets motor appliance apps
Diodes Incorporated has introduced the DGD0579U high-side and low-side gate drivers. This high-frequency device, which has a built-in bootstrap diode, is capable of driving two N-channel MOSFETs in the half-bridge configurations that are commonly used for motor control and DC-DC power delivery functions. It targets high power applications, like cordless power tools, e-bikes, and autonomous […]
Class-D stereo amplifier drives 12 W and 4Ω speakers
Diodes Incorporated introduces the PAM8965 Class-D stereo audio power amplifier with an integrated synchronous boost converter. This high-efficiency device is targeted for use in AI-enabled speaker systems and portable musical instruments – where elevated output power, extended battery life, and compact construction are all key requirements. Running off a 2.8V to 8.5V supply, the PAM8965 has […]
Reducing ringing or reflections by controlling impedance lines
What is a controlled impedance line? For one thing, the term has to do with Printed Circuit Board (PCB) traces and layouts, which get more complex with higher frequency signals. Generally, you need not worry much about controlling impedance in traces unless you are working with signals at or above 50 MHz. However, most of […]
Two-wire, hall effect switches operate over -40 C to 150 C
Diodes Incorporated has announced a family of automotive-compliant, two-wire unipolar (AH323xQ/4xQ) and latch (AH327xQ/8xQ) switch integrated circuits (ICs) that provide high sensitivity and high stability over wide operating voltage and temperature ranges. The ICs are for use in automotive proximity- and position-sensing applications, including seatbelt buckle, power window, gear selector, and seat position. The adoption […]
