COUT Auto-Discharge Function
CE6218 series can discharge the electric charge in the output capacitor (COUT), when a low
signal to the CE pin, which enables a whole IC circuit turn off, is inputted via the N-channel
transistor located between the VOUT pin and the VSS pin (cf. BLOCK DIAGRAM). The COUT
auto-discharge resistance value is set at 100Ω (VOUT=3.0V @ VIN=5.0V at typical). The
discharge time of the output capacitor (COUT) is set by the COUT auto-discharge resistance (R)
and the output capacitor (COUT). By setting time constant of a COUT auto-discharge
resistance value [RDISCHRG] and an output capacitor value (COUT) as τ τ=C x RDISCHRG), the
output voltage after discharge via the N-channel transistor is calculated by the following
formulas.
V = VOUT(E) x e –t/τ, or t=τIn ( V / VOUT(E) )
( V : Output voltage after discharge, VOUT(E) : Output voltage, t: Discharge time,
τ: COUT auto-discharge resistance RDISCHRG×Output capacitor (COUT) value C)
