cause the system to be reset. The system enable  
output prevents critical control functions being  
activated until software has successfully cleared the  
watchdog three times. Such a security could be used  
to prevent motor controls being energized on  
repeated resets of a faulty system.

Description  
The A6150 offers a high level of integration by combining  
voltage regulation, voltage monitoring and software  
monitoring in an 8 lead package. The voltage regulator  
has a low dropout voltage (typ. 380 mV at 100 mA) and a  
low quiescent current (175 µA). The quiescent current  
increases only slightly in dropout prolonging battery life.  
Built-in protection includes a positive transient absorber for  
up to 60 V (load dump) and the ability to survive an  
unregulated input voltage of –20 V (reverse battery). The  
input may be connected to ground or a reverse voltage  
without reverse current flow from the output to the input. A  
comparator monitors the voltage applied at the VIN input  
comparing it with an internal 1.52 V reference. The power-  
on reset function is initialized after VIN reaches 1.52 V and  
takes the reset output inactive after TPOR depending of  
external resistance. The reset output goes active low when  
the VIN voltage is less than 1.52 V. 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. If
