control their high-power supply
systems,” said Ed Lam, senior
director of IDT’s Power Business
Unit. “The ZSPM1363 is a high-
performance digital power controller
that delivers design flexibility to
reduce development cost and
time to market. And because we
developed it using automotive
design methodology, the chip is
rugged and highly reliable, with
operating temperatures up to
125°C.”
The ZSPM1363 features simple
resistor-based
compensation
adjustment after programming if
load condition changes; there’s no
need to reprogram the chip. And its
multi-programmable compensation
architecture achieves fast transient
response while providing low ripple,
steady state performance.

New 36V Op Amps from
STMicroelectronics Raise
Ruggedness, Stability, and
Efficiency in Automotive and
Industrial Applications
STMicroelectronics has introduced
two 36V op amps that deliver
enhanced
performance
and
ruggedness in automotive and
industrial applications. The op
amps feature a wide supply-voltage
range, stability in challenging
operating conditions, and tolerance
of electrostatic discharge (ESD) up
to 4kV (HBM1).
The TSB572 and TSB611 single
op amps are the first devices
produced using ST’s new 40V-ready
BiCMOS2 semiconductor process.
This technology delivers superior
GBW/Icc3 efficiency resulting
in about five times lower supply
current in relation to performance,
compared with standard op amps.
In addition, low input-offset voltages
with temperature drift below 6µV/°C
simplify system design, eliminate
any need for trimming or calibration,
and ensure consistent performance
over the specified temperature
range -40°C to 125°C.
The TSB572, with rail-to-rail inputs
and output, has 2.5MHz gain-
bandwidth (GBW) and 1.5mV
maximum input-offset voltage. The
op amp is stable with capacitive
loads and highly resistant to phase
reversal. Its broad supply-voltage
range, from 4.0V to 36V, allows
reliance on specified parameters
with a wide variety of power
supplies.
The TSB611 has 560kHz GBW and
can operate from a supply voltage
as low as 2.7V. It is a unity-gain-
stable device, and has extremely
low input-offset voltage of 1mV as
well as frugal operating current of
125µA (max.) at 36V.
Compact package options make
ST’s new op amps ideal for use
where space is tight, such as in
automotive audio systems and
Electronic Control Units (ECUs).
The TSB572 is in mass production
now in 3mm x 3mm DFN or Mini-
SO8, priced from $0.80. The
TSB611 in SOT23-5 is also in mass
production, priced from $0.55 for
orders of 1000 pieces.
