drivers for portable and battery-powered applications that ST introduced last year: the STSPIN220 for stepper motors, STSPIN230 for three-phase brushless motors, and STSPIN240 for brushed DC motors up to 1.3A. The STSPIN family now presents designers with a choice of compact, convenient, and energy-efficient drivers for the motor types most commonly used in portable applications, contributing to the widespread adoption of battery-powered IoT devices. A complete ecosystem is ready to support fast and easy evaluation and prototyping with the STSPIN250, and comprises anSTM32Nucleoexpansionboard (X-NUCLEO- IHM13A1) and related software tools (X-CUBE-SPN13) that connect motor-control projects with the extensive STM32Cube MCU-development resources. The STSPIN250 is in production now in the 3mm x 3mm VQFPN package, priced $0.75 for orders of 1000 pieces.

STMicroelectronics Launches Tiny 2.6A Brushed DC Motor Driver for Portable, Battery- Powered IoT Devices The STSPIN250 single-chip 2.6A driver for brushed DC motors extends STMicroelectronics’ family of miniature, low-voltage, energy-efficient drivers for battery-powered portable and wearable applications The driver integrates a full power-MOSFET bridge and fixed off-time PWM current controller in a tiny 3mm x 3mm package that saves space in portable equipment. The low on-resistance of the power stage (200mΩ total, high-side + low-side) and the best-in-the market current-sipping standby mode — below 80nA — help maximize battery runtime and keep equipment-case temperatures down. Its supply-voltage range of 10V to 1.8V allows designers to specify a power source as small as a single Li-ion cell. Brushed DC motors offer a strong combination of performance, cost-effectiveness, and reliability, and are a popular choice of designers in a wide variety of applications. STSPIN250’s high output-current capability allows use in low-to-medium-power applications such as portable printers, POS terminals, consumer devices, electronic valves or door lockers, toys, and medical or wellness devices ranging from electric toothbrushes to syringe pumps. It also has comprehensive built-in protection features including Under-Voltage lockout (UVLO), non- dissipative over-current protection, short-circuit protection, and thermal shutdown. The STSPIN250 joins the three monolithic, low-voltage

New Yorker Electronics Features Mil-Spec Wet Tantalum Capacitor with Extended Capacitance Range New Yorker Electronics is now distributing the Vishay tantalum-cased, hermetically sealed wet tantalum capacitor with the new, expanded capacitance ranges. The new device features a wide voltage range from 50V to 100V, high capacitance from 220µF to 680µF, capacitance tolerance of ±10% and ±20% standard and a maximum ripple current of 2750mA. Offered in the axial T1, T2, T3 and T4 case size, the M39006/33 operates over a temperature range of -55°C to +85°C, to +125°C with voltage derating. It is the industry’s first such device to be qualified to the MIL-PRF-39006/33 specification. MIL-PRF-39006 establishes 1000h failure rate levels of 1%, 0.1%, and 0.01%. For designers, the M39006/33 (Style CLR93) offers established reliability for critical avionics and aerospace systems. The device combines its high capacitance and
