RTQ2082-QT

Automotive CIS/CCM PMIC for Ultra Compact Camera and High Image Quality System

RTQ2082-QT
New

The RTQ2082-QT is a highly integrated PMIC designed for automotive camera applications. It includes three step-down converters and one high PSRR low-dropout (LDO) regulator. The high-voltage step-down converter operates with an input voltage range of up to 18.5V, suitable for Power Over Coax (POC) connections.Two low-voltage step-down converters provide a constant output voltage. All step-down converters operate in a forced fixed-frequency PWM mode.The LDO output voltage can be easily set via an external resistor. For added flexibility, the RTQ2082-QT supports 10 power sequences, configurable through a resistor.The IC is available in a WETD-VQFN-16L 3x3 package with dimple lead type wettable flanks.The recommended junction temperature range is -40°C to 150C, and the ambient temperature range is -40°C to 125°C.
