Functional description

4 Functional description

ApplicationThe IC regulates an input voltage VI in the range of 5.5 V < VI < 40 V to a nominal output voltage of VQ = 5.0 V. A reset signal is generated for an output voltage of VQ < VRT (typ. 4.5 V). The reset delay can be set with anexternal capacitor. The device has two logic inputs. A voltage of VE2 > 4.0 V applied to the E2-pin (e.g. byignition) turns the device on. Depending on the voltage on pin E6 the IC may be kept in Hold active-state evenif VE2 goes to low level (see Table 6). This makes it simple to implement a self-holding circuit without externalcomponents. When the device is turned off, the output voltage drops to 0 V and current consumption tendstowards 0 μA.

Design notes for external componentsThe input capacitor CI is necessary for compensation of line influences. The resonant circuit consisting of leadinductance and input capacitance can be damped by a resistor of approximately 1 Ω in series with CI. Theoutput capacitor is necessary for the stability of the regulating circuit. Stability is specified at values ofCQ ≥ 22 μF and an ESR of ≤ 3 Ω within the operating temperature range.

Circuit descriptionThe control amplifier compares a reference voltage, which is kept highly accurate by resistance adjustment,to a voltage that is proportional to the output voltage and drives the base of the series transistor via a buffer.Saturation control as a function of the load current prevents any over-saturating of the power element.The reset output RO is in high-state if the voltage on the delay capacitor CD is greater or equal VUD. The delaycapacitance CD is charged with the current ID for output voltages greater than the reset threshold VRT. If theoutput voltage drops below VRT a fast discharge of the delay capacitor CD sets in and as soon as VCD drops belowVLD the reset output RO is set to low-level (see Figure 6). The reset delay can be set within a wide range bydimensioning the capacitance of the external capacitor.
