STMicroelectronics Evaluation Board Half-Bridge Driver for EVAL-L99DZ100G for Door Zone Applications

The EVAL-L99DZ100G and EVAL-L99DZ120 are evaluation boards designed for Door Zone Applications. Both are composed by the same motherboard and they differentiate for the daughter board on which is pre-assembled the L99DZ100G in the EVAL-L99DZ100G case (conceived for front door application) or the L99DZ120 in the EVAL-L99DZ120 case (conceived for rear door applications).

• Internal 10bit PWM timer for each stand-alone HS driver
• Buffered supply for voltage regulators and 2 high-side drivers (OUT15 & OUT_HS / both P-channel) to supply e.g. external contacts
• Programmable soft-start function to drive loads with higher inrush currents as current limitation value (for OUT1-6, OUT7, OUT8 and OUT_HS) with thermal expiration feature
• Control block for electro-chromic element (not present in L99DZ120)
• Two 5 V voltage regulators for microcontroller and peripheral supply
• Configurable window watchdog
• LIN 2.2a compliant (SAEJ2602 compatible) transceiver
• Advanced high speed CAN transceiver with local failure and bus failure diagnosis and selective wake-up functionality (not present in L99DZ120)
• Separated (Isolated) fail-safe block with 2 LS (RON = 1 mΩ) to pull down the gates of the external HS MOSFETs
• Thermal clusters
• A/D conversion of supply voltages and internal temperature sensors
• Embedded and programmable VS duty cycle adjustment for LED driver outputs
