Fairchild Semiconductor’s 20V Single P-Channel PowerTrench® MOSFETs Improve Portable Device Battery Charging and Load Switching

To help designers of cellular handsets and other portable applications improve battery charging and load switching, Fairchild Semiconductor (NYSE:FCS) has expanded its line of P-Channel PowerTrench® MOSFETs.

The FDMA910PZ and FDME910PZT feature the MicroFET™ MOSFET package and provide exceptional thermal performance for their physical size (2 x 2 mm & 1.6 x 1.6 mm), making them well suited for switching and linear mode applications. Available with a 20V rating, the devices offer low on-state resistance. To prevent electrostatic discharge (ESD) failures, the FDMA910PZ and FDME910PZT are equipped with optimized Zener diode protection, which also reduces IGSS leakage maximum rating from 10µA to 1µA.

Features and Benefits:

FDMA910PZ
  •     Max RDS(ON) = 20 mΩ at VGS = -4.5V, ID = -9.4A
  •     Max RDS(ON) = 24 mΩ at VGS = -2.5V, ID = -8.6A
  •     Max RDS(ON) = 34 mΩ at VGS = -1.8V, ID = -7.2A
  •     Low profile - 0.8 mm maximum in the  MicroFET 2 x 2 mm package with HBM ESD protection level > 2.8kV typical
FDME910PZT
  •     Max RDS(ON) = 24mΩ at VGS = -4.5V, ID = -8A
  •     Max RDS(ON) = 31mΩ at VGS = -2.5V, ID = -7A
  •     Max RDS(ON) = 45mΩ at VGS = -1.8V, ID = -6A
  •     Low profile: 0.55 mm maximum in the  MicroFET 1.6 x 1.6 mm Thin Package with HBM ESD protection level > 2kV typical
The FDMA910PZ and FDME910PZT are free from halogenated compounds and antimony oxides and are RoHS-compliant. Both devices provide safe operation at low-voltage and are suitable for use in handsets and portable devices.

Fairchild Semiconductor is a mobile technology leader offering a substantial portfolio of analog and power IP that can be customized to meet specific design requirements. By integrating leading circuit technologies into tiny, advanced packages, Fairchild provides mobile users significant advantages while reducing the size, cost and power of designs. Fairchild’s mobile IP can be found in a majority of handsets in use today.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

Model QLS Quad Loop Splitter Splits One 4-20 mA Current Loop into 4 Independent Loops

Image
Model QLS Quad Output Loop Splitter / Retransmittersources up to four (4) independently adjustable 4-20 mA outputs from a single input, which can be 4-20 mA, 1-5V, 0-5V or 0-10V, as selected by jumpers. The outputs can share a common ground. The input and outputs are mutually isolated to ±10V by means of active circuitry to accommodate differences in local grounds with normal industrial grounding practices. If any device in an output loop is removed from a loop or fails, or if a wiring fault occurs, the other loops continue to operate properly. Each loop only drives a single load, avoiding compliance problems. Model QLS overcomes problems associated with the common industrial wiring practice where the same 4-20 mA signal from a transmitter is sent to multiple devices in series. In such a circuit, the devices in the loop cannot share a common ground, but must be electrically floating, which is often not possible. When any device in the loop is removed, fails or if a wiring fault occur
