MB4214 General Description

The MB4214 contains reference voltage circuit, oscillator, divider and comparator as shown in Fig. 1. Oscillator frequency is arbitrary controlled by external resistor RT, capacitor CT and VS input voltage.

Divider consists of 13 stages of divider circuit which is constructed by IIL (Intergrated Injection Logic) technique. It expands the oscillator period up to 4096times. About 100hours period is achieved by a small capacitor.

Free Running Oscillation (Long period low frequency) is achieved when OSC/FR pin is connected to GND.

MB4214 Maximum Ratings

(See NOTE) (TA=25°C)

Rating	Symbol	Value	Unit
Power Supply Voltage	VCC	18	V
Zener Current	IZ	20	mA
Input Voltage	VIN	-0.3 to 18 (VINVCC)	V
Output Voltage	VO	18	V
Power Dissipation	PD	620 (TA85°C)	mW
Operating Temperature	TA	-30 to +85	°C
Storage Temperature	TSTG	-55 to +125	°C

NOTE: Permanent device damage may occur if the above Absolute Maximum Ratings
           are exceeded. Functional operation should be restricted to the conditions
           as detailed in the operational sections of this data sheet. Exposure to
           absolute maximum rating conditions for extended periods may affect device
           reliability.
