PIN NAME

PIN FUNCTION

26

CK

power−on reset timer.

27

MSCK

To input clock pulses, one−shot pulses can be generated for CK (26 pin) inputs at the rise

edge. When the pin is not used, short it with GND.

28

TC

Time setting pin for the reset and watchdog timers.

29

RESET

NPN transistor open−collector output.

(1) The signal goes low when the output voltage drops below the specified 92% (TD62650 /

652) or 85% (651) level.

(2) The pin generates a reset signal that is determined by the external condenser connected

to the TC pin.

(3) The pin generates reset pulses intermittently if no clock is attached to the CK pin.

This function can be used as a watchdog timer for microcomputers.

30

ADJ

Output voltage adjusting pin. The voltage will increase when a resistor is connected between

ADJ and GND (1 pin). It can reduce the voltage when the resistor is inserted between ADJ
