H9108
The H9108 is a high frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a very compact solution to achieve a 2A continuous output current over a wide input supply range, with excellent load and line regulation.The H9108 requires a minimal number of readily available, external components and is available in a space saving
SOT23-6 package .
H9008
The H9008 is a high-efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The device is available in an adjustable version. Supply current with no load is 40uA and drops to <1uA in shutdown. The 2.5V to 5.5V input voltage range makes the H9008 ideally suited for single Li-Ion battery powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. PWM/PFM mode operation provides very low output ripple voltage for noise sensitive applications.Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. Low output voltages are easily supported with the 0.6V feedback reference voltage. The H9008 requires a minimal number of readily available, external components and is available in a space saving SOT23-5 package.
SSP721A
SSP721A is a single chip transceiver developed for Meter-Bus standard (EN1434-3、EN13757) applications.
The SSP721A interface circuit adjusts the different potentials between a slave system and the Meter-Bus master. The connection to the bus is polarity independent and supports full galvanic slave isolation with optocouplers. The circuit is supplied by the master via the bus. Therefore, this circuit offers no additional load for the slave battery. A power-fail function is integrated. The receiver has dynamic level recognition, and the transmitter has a programmable current sink. A 3.3V voltage regulator, with power reserve for a delayed switch off at bus fault, is integrated.
SSP1922
SSP1922 is a high accurate time measurement (TDC) circuit. SSP1922 integrates analog comparator, analog switch, Schmidt flip-flop and other internal devices, thus greatly simplifying the peripheral circuit. At the same time, the first wave detection function is added inside, so that the anti-interference ability is greatly improved. The programmable offset range of the comparator is increased to ±35mV, the sampling accuracy can be improved.Measuring the relative pulse width of the first wave gives the user an indication of the strength of the received signal. Through this hint, we can judge the abnormal detection of ultrasonic transducer, the increase of wall covering, the presence of bubbles in water and so on. The Start-TOF-Restart command can complete a measurement of ultrasonic time difference (upstream and downstream) and data reading, so as to greatly reduce the software operation and power consumption. Compatible with TDC – GP22.
SSP1120
The SSP1120 is a precision, 16-bit, analog-to-digital converter (ADC) that offers many integrated features to reduce system cost and component count in applications measuring small sensor signals.
The device can perform conversions at data rates up to 2000 samples-per-second (SPS) with single-cycle settling. At 20 SPS, the digital filter offers simultaneous 50-Hz and 60-Hz rejection for noisy industrial applications. The internal PGA offers gains up to 128 V/V. This PGA makes the SSP1120 ideally suited for applications measuring small sensor signals, such as resistance temperature detectors (RTDs), thermocouples, thermistors, and bridge sensors.
Power consumption is as low as 120 µA@3.3V when operating in duty-cycle mode with the PGA disabled.
The SSP1120 is offered in a TSSOP-16 package and is specified over a temperature range of –40°C to +125°C.

PM004MNIA
A novel non-volatile magnetic memory MRAM is an ideal device for non-volatile cache and main memory. The application prospect is not limited to the traditional computer storage system, but also can be extended to many other fields, and is even expected to become a general memory.
MRAM ensures that data will not be lost in the case of power failure and can prevent data damage caused by rays. In emerging applications such as the Internet of Things and big data, ubiquitous sensor terminals need to collect massive data. In order to save storage power, MRAM has become a popular candidate for its relatively good performance.
78LXX
78LXX is three-terminal positive regulators. One of these regulators can deliver up to 100mA of output current. The internal limiting and thermal-shutdown features of the regulator make them essentially immune to overload. When used as are placement for a zener diode-resistor Combination, an effective improvement in output impedance can be obtained, together with lower quiescent current.
