XC6221B series can discharge the electr ic charge in the output capacitor (c l ), when a low signal to the ce pin, which enables a whole ic circuit turn off, is inputt ed via the n-channel transistor located between the v out pin and the v ss pin (cf. block diagram). the cl auto-discharge resistance value is set at 780
(v out =4.0v @ v in =6.0v at typical). the discharge time of the output capacitor (c l ) is set by the cl auto-discharge resistance (r) and the output capacitor (c l ). by setting time constant of a c l auto-discharge resistance value [rdischg] and an output capacitor value (c l ) as ( =c x rdischg), the output voltage after di scharge via the n-channel transistor is calculated by the following formulas. v = v out(e) x e ?t/ , or t= in ( v / v out(e) ) ( v : output voltage after discharge, v out(e) : output voltage, t: discharge time, : c l auto-discharge resistance rdischg output capacitor (c l ) value c)
9/23 xc6221 series operational explanation (continued) the xc6221 series? foldback circuit operates as an output current limiter and a short protection of the output pin. when the load current reaches the curr ent limit level, the fixed cu rrent limiter circuit operates and output voltage drops. when the output pin is shorted to the v ss level, a current of about 30ma flows. the ic's internal circuitry can be shutdown via the signal from the ce pin with the xc6221 series. in shutdown mode, output at the v out pin will be pulled down to the v ss level via r1 & r2. however, as for the XC6221B series, the c l auto-discharge resistor is connected in parallel to r1 and r2 while the power supply is applied to the v in pin. therefore, time until the v out pin reaches the v ss level becomes short. the output voltage becomes unstable, when the ce pin is open. if this ic is us ed with the correct output voltage for the ce pin, the logic is fixed and the ic will operate normally. however, supply current may increase as a resu lt of through current in the ic's internal circuitry when medium voltage is input. 1 . please use this ic within the stated absolute maximum ratings . the ic is liable to malfunction should the ratings be exceeded. 2. where wiring impedance is high, oper ations may become unstable due to noise and/or phase lag depending on output current. please wire the input capacitor (c in ) and the output capacitor (c l ) as close to the ic as possible. notes on use
