AN8021SB Features
· It operates at a control frequency up to 700 kHz, realizing the output rise time of 35 ns and the output fall time of 25 ns.
· Pre-start operating current is as small as 70 mA (typical) so that it is possible to use a miniaturized start resistor.
· Output block employs totem pole method.
The absolute maximum rating of ±1.0 A (peak) allows the direct drive of power MOSFET.
· Built-in pulse-by-pulse overcurrent protection circuit
· Built-in protection circuit against malfunction at low ltage (on/off: 14.2 V/9.2 V)
· Equipped with timer latch function and overvoltage protection circuit.
· Two kinds of packages: 9-pin SIP, 16-pin SOP
