MC34160/D
MC34160, MC33160
100 mA, 5.0 V Voltage
Regulator and Supervisory
Circuit for Microprocessors
The MC34160 Series is a voltage regulator and supervisory circuit
containing many of the necessary monitoring functions required in
microprocessor based systems. It is specifically designed for
appliance and industrial applications, offering the designer a cost
effective solution with minimal external components. These
integrated circuits feature a 5.0 V/100 mA regulator with short
circuit current limiting, pinned out 2.6 V bandgap reference, low
voltage reset comparator, power warning comparator with
programmable hysteresis, and an uncommitted comparator ideally
suited for microprocessor line synchronization.
Additional features include a chip disable input for low standby
current, and internal thermal shutdown for over temperature protection.
These devices are contained in a 16 pin dual−in−line heat tab
plastic package for improved thermal conduction.
