AO4821 Datasheet | Alpha & Omega Semiconductors

Description The AO4821 uses advanced trench technology to provide excellent RDS(ON), low gate charge and operation with gate voltages as low as 1.8V. This device is suitable for use as a load switch or in PWM applications. It is ESD protected. Standard Product AO4821 is Pb-free (meets ROHS & Sony 259 specifications). AO4821L is a Green Product ordering option. AO4821 and AO4821L are electrically Features VDS (V) = -12V ID = -8 A (VGS = -4.5V) RDS(ON) < 18mΩ (VGS = -4.5V) RDS(ON) < 22mΩ (VGS = -2.5V) RDS(ON) < 29mΩ (VGS = -1.8V) ESD Rating: 4KV HBM D1 S2 G2 S1 G1 ..
