PRODUCTION DATA
Typical limits are for TJ = 25°C only, represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only; minimum and maximum limits apply over the junction temperature range of –40°C to 125°C. Unless otherwise specified, the following conditions apply: VIN = 48 V, VCC = 7.4 V, VCCX = 0 V, EN = 5 V, RT = 16 k?, no load on LO and HO.
