EVQ6620A-QN-00A

The EVQ6620A-QN-00A is an evaluation board designed to demonstrate the capabilities of the MPQ6620A-AEC1, an eight-channel, automotive pre-driver with internal pulse-width modulation (PWM) generators and an serial peripheral interface (SPI).  

The MPQ6620A-AEC1 integrates a charge pump to drive an external N-channel MOSFET for reverse battery protection. The high-side (HS) gate drive is generated by the charge pump, which allows for 100% duty cycle operation. 

The MPQ6620A-AEC1 integrates eight independent PWM generators that can be applied to the corresponding outputs, greatly reducing the dependence on a microcontroller (MCU). Two built-in current-sense (CS) amplifiers can be used for HS, low-side (LS), and in-line current-sensing. 

Internal safety features and diagnostic functions include short-circuit protection (SCP), under-voltage lockout (UVLO) protection, over-voltage protection (OVP), open-load detection (OLD), over-temperature warning (OTW), over-temperature shutdown (OTS), and gate drive fault (GDF) protection.  

The MPQ6620A-AEC1 is available in a QFN-48 (7mmx7mm) package with wettable flanks. It is suitable for automotive power seats, lift gates, sunroofs, adaptive suspensions, and brushed DC motor drivers.
