SLLIMM-nano is a small, low-loss, intelligent molded module with optional extra features, which meets the increasing energy saving, compactness, reliability and system cost requirements for variable speed motor control market in home appliances (such as dishwashers, refrigerator compressors, air conditioner fans, draining and recirculation pumps) and low power industrial applications (such as small fans, pumps and tools, etc.).

The L6234 is a high performance DMOS power device, manufactured using Multipower BCD60II technology, and can be used in a wide range of applications. It has a wide input voltage range and a high output current.

This application note provides information on how to protect the L6203 driver IC from short circuits

This document introduces the L293, L293E and L298N dual-bridge ICs, which can simplify the design and improve the efficiency of constant-current choppers.

The L6506 is a linear integrated circuit designed to sense and control the current in stepping motors and other similar devices. When used in conjunction with power stages like the L293, L298N, or L7180, the chip set forms a constant current drive for inductive loads and performs all the interface functions from the control logic through the power stage. The L6506 may be used with either two phase bipolar or four phase unipolar motor configurations.

This document describes the common requirement of executing a relative move in operating a stepper motor system. The move is usually specified as a fixed number of basic motor steps in the clockwise or counter-clockwise direction. It is common practice to execute this move along a trapezoidal shaped velocity vs. time profile. This profile is determined by the number of steps to be moved and the required accel, decel, and peak speed. Very often system designers require that a move be made in the shortest time possible and in these cases the accel, decel and peak speed are set to the maximum that the system can achieve. Given the move distance, accel, decel, and peak speed requirement, a profile can be determined. Since the control structure of the practispin software is designed such that the velocity and accel/decel rate can be changed at will, the task of pre-calculating the velocity profile boils down to determining the position values where operation switches from accel to constant speed and then from constant speed to decel. Since this is a relative move, we can assume that motion starts at position = 0, time = 0, and velocity = 0.

The L6225, L6226, L6227 are dual full-bridge driver ICs specifically developed to drive a wide range of motors. These ICs are one-chip, cost-effective solutions that include several unique circuit design features. These features allow the devices to be used in many applications including DC and stepper motor driving.

This application note describes the EVAL6470 demonstration board, which is used to demonstrate the L6470 fully integrated microstepping motor driver.

This application note describes the demonstration board of the DMOS driver for the three-phase brushless DC motor driver L6230Q. The board implements a typical application which can be used as a reference design to drive three-phase brushless DC motors with currents up to 1 A DC.

AN4144 is an application note published by ST, which introduces the principle and parameter optimization method of voltage mode driving.

This application note provides information regarding common I/O operation of the MICROWIRE® EEPROM family of products. This information can help designers interface MICROWIRE® EEPROM products with different microcontrollers.

This application note provides a detailed description of the part numbering scheme of Serial EEPROM products. The part numbering scheme consists of a maximum of 13 digits grouped into nine fields (A to H), as shown in Table 1: Serial EEPROM part numbering scheme on page 1Table 1. Fields A to C represent the product identifiers and fields D to H the product options. The “-” character is used to separate the identifiers from the options. An additional “/” followed by two digits are used by ST to aid traceability, and might appear on some documents at the bottom of the Ordering information scheme table under Process. This information offers the die and technology references (for temperature range 3 devices) and can be ignored for temperature range 6 devices.

This application note introduces the dynamic-link library (DLL) that provides the programming interface for the CRX14 USB reader demonstration kit. The CRX14 USB reader demonstration kit is designed to show off the STMicroelectronics short range contactless memory product range. These contactless memories, such as SR176, SRIX512 and SRIX4K, are powered by a transmitted carrier radio wave, at 13.56MHz. The CRX14 USB reader demonstration kit can be controlled via the Universal Serial Bus (USB). The DLL, that is presented here, gives the application developer a wide variety of possibilities for working easily with this demonstration kit, even using just low level commands.

This application note gives an example of how to use the STR71x I2C peripheral to communi- cate with an I2C Protocol-Compatible Electrically Erasable Programmable Read Only Mem- ory (EEPROM).

This document describes the construction and operation of STMicroelectronics' EEPROM, and provides useful guidelines for achieving high reliability applications under some of the most stringent conditions, such as those experienced in the automotive market.
