Nanopower Comparator

TLV3691The TLV3691 comparator offers a wide supply range, low quiescent current, and rail-to-rail inputs. These features come in industry-standard and extremely small packages, making this device ideal for low-voltage and low-power applications.

Available as a single channel, the comparator’s low power, wide supply, and temperature range make the device flexible enough to handle applications from consumer to industrial. The TLV3691 is available in SC70-5 and 1-mm × 1-mm DFN-6 packages. This device is specified for operation across the –40°C-to-125°C expanded industrial temperature range.

The TLV3691’s features include a 24-µs response time, push-pull output, and a range that extends 100 mV beyond both rails. Texas Instruments offers a variety of tools and resources to speed development with the TLV3691, including a SPICE Model, TINA-TI SPICE Model, and the DIP adapter evaluation module.

Nanopower Anisotropic Magnetoresistive Sensor ICs

HoneywellThe ultra-high sensitivity SM351LT and the very high sensitivity SM353LT nanopower anisotropic magnetoresistive sensor ICs provide a high level of magnetic sensitivity (as low as 7 Gauss typical) while requiring nanopower (360 nA). The high sensitivity improves design flexibility and provides application cost savings by utilizing smaller or lower-strength magnets. The nanopower enables the ICs to be used in battery-operated equipment with extremely low power requirements.

The SM351LT and the SM353LT are designed for a range of battery-operated applications including water, gas, and electricity meters; industrial smoke detectors; exercise equipment; security systems; handheld computers; and scanners. They can also be used with household appliances (e.g., dishwashers, microwaves, washing machines, refrigerators, and coffee makers), medical equipment (e.g., hospital beds, medication dispensing cabinets, and infusion pumps), and consumer electronics (e.g. notebook computers, tablets, and cordless speakers).

The ICs’ omnipolarity enables them to be activated by either a north or south pole, eliminating the need for the magnet polarity to be identified. This simplifies installation and potentially reduces the system cost. The push-pull (CMOS) output does not require external resistors, making it easier to operate. The non-chopper stabilized design eliminates electrical noise generated by the sensor. The subminiature SOT-23 surface-mount package is smaller than most reed switches and can be used in automated pick-and-place component installation.
