TCA5600
TCF5600
Universal Microprocessor
Power Supply/Controllers
The TCA5600, TCF5600 are versatile power supply control circuits for
microprocessor based systems and are mainly intended for automotive
applications and battery powered instruments. To cover a wide range of
applications, the devices offer high circuit flexibility with a minimum of
external components.
Functions included in this IC are a temperature compensated voltage
reference, on–chip dc/dc converter, programmable and remote controlled
voltage regulator, fixed 5.0 V supply voltage regulator with external PNP
power device, undervoltage detection circuit, power–on RESET delay and
watchdog feature for safe and hazard free microprocessor operations.
• 6.0 V to 30 V Operation Range
• 2.5 V Reference Voltage Accessible for Other Tasks
• Fixed 5.0 V ± 4% Microprocessor Supply Regulator Including Current
Limitation, Overvoltage Protection and Undervoltage Monitor.
• Programmable 6.0 V to 30 V Voltage Regulator Exhibiting High Peak
Current (150mA), Current Limiting and Thermal Protection.
• Two Remote Inputs to Select the Regulator’s Operation Mode:
OFF = 5.0 V, 5.0 V Standby
Programmable Output Voltage
• Self–Contained dc/dc Converter Fully Controlled by the Programmable
Regulator to Guarantee Safe Operation Under All Working Conditions
• Programmable Power–On RESET Delay
• Watchdog Select Input
• Negative Edge Triggered Watchdog Input
• Low Current Consumption in the VCC1 Standby Mode
• All Digital Control Ports are TTL and MOS–Compatible
Applications Include:
• Microprocessor Systems with E2PROMs
• High Voltage Crystal and Plasma Displays
• Decentralized Power Supplies in Computer Telecom Systems
