The maximum input voltage is 42 V (65 V/≤ 400 ms). The device can produce an output current of more than 500 m A. It is short-circuit-proof and incorporates temperature protection that disables the circuit at impermissibly high temperatures. Semiconductor Group 1998-11-01 TLE 4261-2 Application Description The IC regulates an input voltage VI in the range 6 V < VI < 40 V to VQrated = 5.0 V. A reset signal is generated for an output voltage VO of < 4.75 V. The reset delay can be set with an external capacitor. A connected microprocessor is monitored by the integrated watchdog circuit; if pulses are missing, the reset output is set low. The pulse repetition rate can be set within wide limits with the capacitor for reset delay. If this input is connected to a voltage of > 6 V, the watchdog function is deactivated. The device also Features an inhibit input, which is activated by a voltage of > 6 V and then works on this input through internal hysteresis up to approx. 3 V. A voltage of < 2 V on the inhibit input turns off the regulator, current drain then dropping to max. 50 µA. Design Notes for External ponents The input...
