Combined smart power IC for VCR with PWM controlled motor voltage

A smart power IC for VCR motor control has been developed combining all functions of three conventional VCR motor drivers, together with additional new features for improved system performance. Filter networks and sensing resistors are no longer required. This is made possible by using BCD technology, which is already state of the art in the automotive and hard disk motor driver applications.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

A 300-A delta V/sub F/ tester

The design and development of a relatively low-cost, high-current, transient thermal resistance tester are described. The tester, which employs delta techniques, was initially used to measure the die bond integrity of large power handling rectifier assemblies, but because of its versatility it can thermally characterize most semiconductor junctions. Circuit design details and testing of several products are illustrated, including the delta V/sub F/ and V/sub F/ measurements of power rectifiers and smart power ICs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

'Merged' technologies: present capabilities and value for applications in high-voltage and 'smart power' circuitry

The multimerged technologies applicable to use in advanced high-voltage and smart power ICs are described. The various combinations of merged process (bipolar with MOS), merged function (sensor with control and logic and/or power), and mixed-signal (analog and digital) are outlined. Related basic tables of electrical ratings and relative merits are contrasted, and key concerns, such as strengths and weaknesses, are mentioned. Additionally, a pair of representative circuit examples, including an innovative system-on-a-chip, are provided. These illustrate and highlight actual prospects for a greater integration of high-voltage and smart power circuitry and concentrate on activities and opportunities such as appliances, automotive, consumer, and industrial products. >

High voltage RESURF LDMOS for smart power integrated circuits

An in-depth comprehension of the electrical behaviour of a RESURF LDMOS is given. Avalanche breakdowns are evaluated leading to simple design rules based on analytical formulations for a first order analysis, and on bidimensional numerical simulations for a second order analysis. A 2D numerical simulator is used to study the influence of some critical parameters on the breakdown voltage and the on behavior. Such parameters include the epitaxy doping and thickness, the channel-drain distance, the channel junction depth. On state investigation is conducted to evaluate the on-resistance and the current flow of the device and to study the improvement which can be expected from technics such as surface doping or SIPOS deposition. With such design rules the RESURF LDMOS is a good applicant for power switches in smart power IC. To illustrate and validate these design rules medium voltage diodes (350-550 volts) are processed and tested.
