(VBAT = 13.6V, VSLEEP = 5V, IN1 = IN2 = no connection, RSET = 61.9kΩ to BAT, RPU = 10kΩ at DOUT1 and DOUT2, RL = 5kΩ to

GND at AOUT1 and AOUT2, unless otherwise noted, TA = -40ºC to +125ºC. Typical values are at TA = +25ºC.) (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 20µs.
