EM6152 - 5V Automotive Regulator

General Description

The EM6152 offers a high level of integration by combining voltage regulation, voltage monitoring and software monitoring using a windowed watchdog.

A comparator monitors the voltage applied at the VIN input comparing it with an internal voltage reference VREF.

R EM MICROELECTRONIC - MARIN SA EM6152 5V Automotive Regulator with Windowed Watchdog Description The EM6152 offers a high level of integration by combining voltage regulation, voltage monitoring and software monitoring using a windowed watchdog. A comparator monitors the voltage applied at the VIN input comparing it with an internal voltage reference VREF. The power-on reset function is initialized after VIN reaches VREF and takes the reset output inactive after a delay TPOR depending on external resistance ROSC. The reset output goes active low when the VIN voltage is less than VREF. The RES and EN outputs are guaranteed to be in a correct state for a regulated output voltage as low as 1.2 V. The watchdog function monitors software cycle time and execution.
