STMicroelectronics Evaluation Boards 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
