This input signals is bidirectional so it must be converted to a positive signal bacause the L uses a single supply voltage. Datzsheet motor continues to run at rop speed but under closed-loop control. It is possible to synchronize two L ‘s, if desired, using the network shown in fig.

Input Offset Voltage pin 6. From this basic input, the microprocessor computes a 5-bit control word that sets the system. Motor current is regulated by an internal loop xatasheet the L which l2292 performed by the resistors R18, R This section has been added in order to help the designer for the best choise of the values of external. In this case, during the rise-time of the motor current, The L works is open-loop condition. The motor continues to run at rop speed but under closed-loop control.

L292 Datasheet

The transfer function 3 can be written as follows: The large step signal response is limited by slew-rate and inductive load. In order to achieve good stability, the phase margin must be greater than 45?

The interval between one side adtasheet the bridge switching off and the other switching on, t, is programmed by.

It is intended for use, together. The optical encoder also provides an out. The pulse width modulated signal. It is continuosly updated on the motor.

The above function is performed by amplifying the input signals in A.

Small Signal Step Response normalized amplitude vs. These inputs may be used for a variety of applications such as datashee inhibit during reset of the logical. Sensing Rsistor Voltage Drop. Copy your embed code and put on your site: This is accomplished by the first stage – the level shifter, which uses an internally generated 8 V reference.

In order to be sure that the current loop is stable the following condition is imposed: The cutoff frequency is: The module of the transfer function is: STMicroelectronics acknowledges the trademarks of all companies referred to in this document. The braking is applied pro. Voltage and current characteristics: The previous linear analysis is correct for this example.

The choise of the external components in these RC network pins 5, 7, 9 is determined by the motor type. Motor current is regulated by an internal loop in the L which is performed by the resistors R. This is accomplished by the first stage – the level shifter.

The schematic diagram used for the Laplace analysis of the system is shown in fig. The enable inputs were implemented in this way because they are intended to be driven directly by a microprocessor. Search field Part name Part description.
