Notes  
1. RESET is an open drain (open collector) output with an internal pull-up resistor.  
2. ESD testing is performed in accordance with the Human Body Model (HBM) (CZAP = 100 pF, RZAP = 1500 ), the Machine Model (MM)  
(CZAP = 200 pF, RZAP = 0 ), and the Charge Device Model (CDM), Robotic (CZAP = 4.0pF).  
3. Maximum power dissipation at indicated ambient temperature in free air with no heatsink used.  
4. Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may  
cause malfunction or permanent damage to the device.  
5.  
R
is dependent on customer application and PCB layout.
