具備所有必要汽車防護之 30W ADAS 系統的系統級參考設計
PMP10652
概覽
PMP10652 is a System optimized (CISPR 25 Class 3) 30W design for Surround View ADAS system.
The design has various protections such as Load dump through TVS (ISO pulse testing), Reverse Voltage (Innovative Smart diode with very low Iq), Battery Disconnect Switch with OVP protection (PFET) and is EMI optimized to meet Conductive EMI limits of CISPR25 Class3 (overall) and Class5 upto 30MHz Range.
Input voltage range is between 4.5V to 30V with OVP at 20V and hence will operate in most Cold Cranking conditions.
LM74610 is used for Battery reverse protection which utilizes a charge pump to drive an N-channel FET to provide a resistive path for the bypass current to flow. LM53603Q1 is used as front end DC/DC Buck converter which is 2.2MHz switching, Synchronous rectified Wide Vin Buck Converter which can take transient upto 42V. TPS57114Q1 is used to provide power to the cores and it is a high current 2,2MHz switching buck converter. LM26420 is a dual 2.2MHz switching buck converter which is used for generating other required supplies.
LM3880 sequencer is used for all the power up and power down sequencing requirements.
