This high voltage N-channel Power MOSFET is part of the MDmesh DM2 fast recovery diode series. It offers very low recovery charge and time (Qrr, trr)combined with low RDS(on), rendering it suitable for the most demanding high efficiency converters and ideal for bridge topologies and ZVS phase-shift converters.

The new MDmesh™ M6 technology incorporates the most recent advancements to the well-known and consolidated MDmesh family of SJ MOSFETs. STMicroelectronics builds on the previous generation of MDmesh devices through its new M6 technology, which combines excellent RDS(on)per area improvement with one of the most effective switching behaviors available, as well as a user-friendly experience for maximum end-application efficiency.

The STWD100 watchdog timer circuits are self-contained devices which prevent system failures that are caused by certain types of hardware errors (such as, non-responding peripherals and bus contention) or software errors (such as a bad code jump and a code stuck in loop). The STWD100 watchdog timer has an input, WDI, and an output,WDO. The input is used to clear the internal watchdog timer periodically within the specified timeout period, twd. While the system is operating correctly, it periodically toggles the watchdog input, WDI. If the system fails, the watchdog timer is not reset, a system alert is generated and the watchdog output,WDO, is asserted. The STWD100 circuit also has an enable pin,EN, which can enable or disable the watchdog functionality. TheENpin is connected to the internal pull-down resistor. The device is enabled if theENpin is left floating.
