Pin Configuration TLE 4473 GV53, TLE 4473 GV52 (top view)
Pin Definitions and Functions (TLE 4473 GV53, TLE 4473 GV52)
Watchdog input; input for watchdog pulses, positive edge
triggered
Reset output for Q2; open collector output
Reset and watchdog output for Q1; open collector output
Output voltage 2 (5 V); block to GND with a capacitor
ESR < 5 Ω at 10 kHz or
Output voltage 1 (3.3 V/2.6 V); block to GND with a capacitor
C
Not connected; connect to GND
Input voltage; block to GND directly at the IC with a ceramic
capacitor.
Inhibit input 1; low level at INH2 and INH1 disables Q2 and Q1
Inhibit input 2; low level disables Q2
Reset Delay 2; connect a capacitor to set reset delay for Q2
Reset Delay 1; connect a capacitor to GND to set reset delay and
watchdog timing for Q1
Ground
Not connected; connect to GND
