High Sensitivity Latching Digital Hall-effect 32314080 Issue A Sensor ICs with Built-in Pull-up Resistors: SS360PT, SS460P, SS460P-T2 Datasheet FEATURES SS460P-T2 Fastest response time in its class High sensitivity Internal pull-up Hall IC design SS460P Latching magnetics Built-in reverse voltage capability Robust design No chopper stabilization SS360PT No additional electronic noise generated by sensor RoHS-compliant material meets directive 2002/95 POTENTIAL APPLICATIONS Medical infusion pumps Ambulatory noninvasive pump pressure Occulsion detection DESCRIPTION Kidney dialysis machines The SS360PT, SS460P and SS460P-T2 High Sensitivity Load and compression sensing Latching Hall-effect Sensor ICs with Built-in Pull-up Resistors Variable tensions control are small, sensitive, and versatile devices that are operated by the magnetic field from a permanent magnet or an PORTFOLIO electromagnet. They are designed to respond to alternating North and South poles. The SS360PT is turned on by a North The SS360PT, SS460P and SS460P-T2 are part of Honeywells pole while the SS460P and SS460P-T2 are turned on by a family of Latching Digital Hall-effect Sensor ICs, including: South pole. SS360NT, SS360ST, SS360ST-10K SS460S, SS460S-T2 These products offer reliable switching points with a high SS361RT, SS461R magnetic sensitivity of 30 Gauss typ. (55 Gauss max.). They SS361CT, SS461C do not use chopper stabilization on the Hall element, providing SS46 a clean output signal and a faster latch response time when compared to competitive high sensitivity Hall-effect latching SS461A, SS466A sensor ICs that do use chopper stabilization. The internal pull-up resistor often eliminates the need for external components, helping to reduce the system cost. These high-performance yet economical sensor ICs are well suited for demanding, cost-sensitive high-volume applications. These products offer reverse polarity protection, deliver a stable output over a wide temperature range, and can operate from a dc supply voltage from 3 Vdc to 24 Vdc. For brushless dc motor manufacturers who need latching sensors with reliable, consistent performance for more efficient and smaller designs, this product responds to low magnetic fields and offers consistent repeatability while delivering faster response times to a change in magnetic field for better motor efficiency. These product are available in three package styles: SS360PT: Miniature SOT-23 surface-mount package supplied on pocket tape and reel which allows for compact design with automated component placement. SS460P : Flat TO-92-style package with straight leads in bulk packaging which allows for a compact PC board layout. SS460P-T2: Flat TO-92-style package with formed leads in ammopack tape-in-box.
