Ultra-low capacitance TVS diodes offer 3.8-V clamping
TDK Corporation has extended its range of TVS (transient voltage suppression) diodes characterized by their extremely low capacitance values for bidirectional overvoltage protection to include the ULC series (Ultra Low Clamping & Capacitance). The SD01005SL-ULC101 (B74111U0033M060) type has a minimum capacitance of ~0.5 pF and the SD0201SL-ULC101 (B74121U0033M060) type of ~0.6 pF, both at 1 […]
Glitch-free power supervisor IC protects low-voltage IoT apps
Designers can now enhance system reliability in low-voltage IoT applications with the Essential Analog MAX16162 nanoPower supervisor with glitch-free power-up from Maxim Integrated Products, Inc. This supervisor IC is the industry’s first to fully assert a system reset through the entire system power supply ramp; thereby eliminating low-voltage glitches during power-up and delivering higher system reliability. […]
Tiny high-power TVS diodes excel at ESD protection
TDK Corporation has released tiny high-power TVS diodes for ESD protection, extending its portfolio of components for bidirectional overvoltage protection of I/O interfaces. The space requirement of the so-called chip-scale package (CSP) is just 400 x 200 µm² (CSP01005) or 600 x 300 µm² (CSP0201), while the package height of just 100 µm is also […]
Inductors target power circuits in wireless earphones
TDK Corporation has developed the PLEA67 Series of inductors for use in true wireless stereo (TWS)* devices. Mass production will begin in March 2021. This new series of inductors is intended for use in power circuits incorporated into wireless earphones used with smartphones, portable players, and similar devices. In addition to an impressive rated current […]
Single-/Multi-cell solar harvester increases runtime in wearable and IoT applications
Designers of space-constrained designs can now significantly increase runtime with the MAX20361 single-/multi-cell solar harvester with maximum power point tracking (MPPT) from Maxim Integrated Products, Inc. . The industry’s smallest solar harvesting solution is ideal for space-constrained applications such as wearables and the emerging internet of things (IoT) applications. Designers are often challenged with the […]
