MOTOROLA ANALOG IC DEVICE DATA
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
