This application report describes an alternative use of the TLC555-Q1 device as a charge pump. The square-wave output switching between the supply voltage and GND with few additional capacitors and diodes makes the device suitable for generating a positive or negative voltage multiplier. Using the TLC555-Q1 device as a charge pump is a cheap and easy solution for doubling, tripling, or inverting the supply voltage.
A charge pump can be used in automotive applications requiring reverse battery protection. A diode can also be used for battery protection; however, it causes a voltage drop and lowers efficiency. The charge pump is also capable of driving a MOSFET transistor with low drain-to-source on resistance.
Charge pumps can be used in a nonsynchronous rectifier when in low dropout mode to cause a high output ripple with light load. The charge-pump output can be connected to the BOOT pin for providing the necessary voltage to drive the upper-pass transistor.
The semi-expert techniques for automating amplifier circuit designs calls for a combination of hard specification requirements and judgement margins. A design tool must support these techniques to zero in on the appropriate operational amplifier (op amp) and external components.
The difficulty is in the detail when selecting amplifiers and external components to meet the performance criteria for the application.
This application report provides a summary of the differences between AM572x Silicon Revision 1.1/2.0 and AM571x Silicon Revision 1.0 high-performance ARM® devices.
The WiFi® technology contrary to the other connectivity solutions
This application report enables easy migration from MSP430F2xx flash-based MCUs to the MSP430FR58xx/FR59xx/68xx/69xx family of FRAM-based MCUs.
This application note describes the usage of the code conversion application delivered with version 2.0.0 (and above) of the MSP432P401R device header files. In these revisions of the MSP432P401R device header files, the coding style has been adapted to CMSIS. This may lead to compilation errors in user code if the code is not converted. MSP430™ style register definitions have also been removed with exception of legacy 16-bit IPs (see msp432p401r_classic.h).
In addition, certain MSP430 style definitions have changed. Therefore, TI recommends that you run the code conversion application even if you do not use CMSIS style definitions.
For details on what has changed in the device headers, see the release notes of the IDE support file packages.
