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
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.
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
