CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTES:
1. θ_JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
2. All voltages are relative to GND, unless otherwise specified.
Electrical Specifications
V_DD = 12V, C_VG = 0.01µF, C_TIM = 0.1µF, R_SENSE = 0.1Ω, C_BULK = 220µF, ESR = 0.5Ω, T_A = T_J = -40°C to
