Monolithic Power Systems (MPS) MP5022A 12V Hot Swap Voltage Controller
Monolithic Power Systems MP5022A 12V Hot Swap Voltage Controller is designed to protect circuitry on the output from transients on the input. MP5022A also protects input from undesired shorts and transients coming from the output. The maximum load at the output is current limited through a sense FET topology. The magnitude of the current limit is controlled by a low-power resistor from the ISET pin to ground. An internal charge pump drives the gate of the power device, allowing for a power FET with a very low ON resistance of 3mΩ.
MEMS resonators are built with SiTime’s unique MEMS First™ process. A key manufacturing step is EpiSeal™ during which the MEMS resonator is annealed with temperatures over 1000°C. EpiSeal creates an extremely strong, clean, vacuum chamber that encapsulates the MEMS resonator and ensures the best performance and reliability. During EpiSeal, a polysilicon cap is grown on top of the resonator cavity eliminating the need for additional cap wafers. As a result, SiTime MEMS resonator die can be used like any other semiconductor die. One result of SiTime MEMS First and EpiSeal manufacturing processes is the capability to integrate SiTime MEMS die with a SOC, ASIC, microprocessor, or analog dies within a package to eliminate external timing components while providing a highly integrated, smaller, cheaper solution to the customer.
