Undervoltage Lockout High-Current Totem-Pole Output Undervoltage
Lockout With Hysteresis Double-Pulse SuppressionThe TL284xB and provide the features that are necessaryto
implement off-line schemes, witha minimum numberof
external components. lockout (UVLO) anda precision
reference thatis Other internal circuits include logicto ensure
latched operation, also provides current-limit control, anda
totem-pole output The output stage, suitable for driving
N-channel MOSFETs,
The TL284xB and TL284x and TL384x with the following
improvements. The while the oscillator discharge currentis
trimmedto 8.3 conditions, the output hasa maximum
saturation voltage
Major differences thresholds and maximum duty-cycle ranges.
Typical UVLO thresholds and TLx844B devices make them ideally
suitedto off-line for the TLx843B and TLx845B devices are
8.4V (on) and 7.6 operateto duty cycles approaching 100%.A
duty-cycle range by the additionof an internal toggle
flip-flop, which blanks devices are characterized for
operation from –40°Cfor operation from 0°Cto 70°C.
