GENERAL DESCRIPTION
The circuit contains five fixed voltage regulators with foldback current protection and one fixed voltage regulator (REGULATOR 1) that also operates during a load dump. In addition, a RESET function (TDA3601Q) or RESET function (TDA3601AQ), timer functions and a logic multiplexer are implemented.

FEATURES
• Six fixed voltage regulators
• Three microprocessor-controlled regulators
• Two VP-state controlled regulators
• One fixed voltage regulator (can operate during load dump or thermal shutdown)
• VP1 supply pin (low current pin)
• VP2 supply pin (high current pin)
• RESET output (TDA3601Q) or RESET output (TDA3601AQ)
• Internally fixed timer of 100 µs
• Externally fixed delay timer
• High ripple rejection
• Flexible leads.

PROTECTION
• Current limit protection for regulator 1
• Foldback current limit protection (regulators 2 to 6)
• Load dump protection
• Thermal protection
• Regulator outputs DC short-circuit-safe to ground, VP and other regulator outputs
• Capable of handling high energy on any of the output pins
• Reverse polarity safe.
