Optimized for cost-sensitive consumer electronics:
TLV496x
The TLV496x-xTA/B series was specifically developed
for the cost-effective, contactless positioning. Typical
applications are BLDC motors in white goods (such as
dishwashers and washing machines), compressors in
air-conditioners, fans in PCs as well as blinds, garden
tools and building security/burglar protection (e. g. door
and window contacts, gates and roller shutters). Despite
the pressure to cut costs, these applications need very
precise Hall latches or Hall switches (unipolar/bipolar)
for temperatures ranging from -40 °C to 125 °C. The
TLV496x-xTA/B versions have a power consumption of
1.6 mAand an ESD protection up to 4 kVH HBM (Human
Body Model). The output has overcurrent protection and
automatically switches off at high temperatures.
Availability and development support
The Hall sensors of all three series are available in
high volume. Development support includes online
simulation tools and application manuals.
More information about Infineon sensors is available at

switches.
STMicroelectronics Reveals Ultra-Tiny
Low-Dropout Regulator in Breakthrough
Bumpless Chip-Scale Package
STMicroelectronics has introduced the LDBL20, a 200mA
Low-Dropout (LDO) regulator in a minuscule 0.47mm
x 0.47mm x 0.2mm chip-scale package that is ideal for
wearable and portable devices and for flexible electronics
such as multifunction connected smart cards.
The LDBL20’s bumpless STSTAMP™ package breaks
through the minimum I/O-area and height limitation imposed
by the diameter of traditional flip-chip solder bumps, enabling
unprecedentedly small footprints and low mounted heights.
The LDBL20 extends ST’s family of compact LDOs, which
includes devices from 2mm x 2mm DFN to a 0.69mm x
0.69mm CSP with 300mA output.
In addition to its size advantage, the LDBL20 is an outstanding
performer. The 200mA output makes it as powerful as
larger devices from other manufacturers. The input voltage
can range from 1.5V to 5.5V, with 200mV typical dropout.
Rejection (PSRR) of 80dB at 100Hz and 50dB at 100kHz
simplifies filtering over a wide frequency range to provide
a stable rail for low-power circuitry in battery-operated
applications. Quiescent current of 20µA no-load, 100µA full-
load, and 0.3µA in standby help maximize efficiency under all
operating conditions.
A wide range of output voltages is available on request, from
0.8V up to 5.0V in 50mV increments. Designers can also take
advantage of built-in features of the LDBL20, which include
logic-controlled electronic shutdown, internal soft-start, and
support for active output-voltage discharge if required.
An evaluation board for the LDBL20, STEVAL-ISB034V1,
is also available, which assists design-in to a wide range
of products such as fitness and blood-pressure monitors,
glucose meters, hearing aids, wearable sensors, smart
headphones, portable audio devices, smart plugs, smart
watches, and smartcards.
The LDBL20 is in production now, priced from $0.25 for orders
of 1,000 pieces.
