Compensation And Characterization Of The TLS223X Phase-Locked Loop
Texas InstrumentsThis document describes the TLS223x servo-combine predriver its state machine phase comparator and voltage-controlled oscillator (VCO).
The TLS223x uses a phase-locked loop (PLL) to commutate a spindle motor. The selection of compensation values ensures the proper operation of the PLL. An example of the selection process for the TLS223x is provided.

Using LDOs and Power Managers in Systems with Redundant Power Supplies
Texas InstrumentsFor reasons of continuity in some systems independent power sources must operate in parallel. The traditional way to connect two ore more power sources in parallel uses isolation diodes. However in situations where the associated voltage drop or the presence of voltage-feedback sensing wires makes using isolation diodes undesirable special types of low dropout voltage regulators (LDOs) and hot-

Adjustment of ESIOSC Oscillator Frequency (Rev. A)
Texas InstrumentsThe MSP430FR698x Extended Scan Interface (ESI) uses two clock sources. These clocks are ACLK and a high-frequency clock generated by the ESI oscillator ESIOSC. ESIOSC is realized as an RC-oscillator and shows a temperature and voltage dependency. However a hardware-supported measurement of ESIOSC frequency and adjustment by software allows compensating for the frequency drift. This application r
