DC ELECTRICAL CHARACTERISTICS (continued)
(VBAT = 13.6V, VSLEEP = 5V, IN1 = IN2 = no connection, RSET = 61.9kI to BAT, RPU = 10kI at DOUT1 and DOUT2, RL = 5kI to
GND at AOUT1 and AOUT2, unless otherwise noted, TA = -40NC to +125NC. Typical values are at TA = +25NC.) (Note 1)
Note 1: All DC specifications are 100% production tested at TA = +25°C. AC specifications are guaranteed by design at TA =
+25°C.
Note 2: Parameters that change with the value of the RSET resistor: IIH, IIL, IIN_HYS, ISC, tBL, tRAMP, tDEL, fMAX, and PR.
Note 3: Following power-up or startup from sleep mode, the start of the blanking period is delayed 20Fs.
