PRODUCTION DATA.
PARAMETER | TEST CONDITIONS | MIN | TYP | MAX | UNIT | |
---|---|---|---|---|---|---|
UV_VIN_R | Undervoltage threshold for VIN. VBUS LDO disables when threshold reached. | VIN rising, TPS66120 only. | 2.45 | 2.75 | V | |
VIN rising, TPS66121 only. | 3.89 | 4.40 | V | |||
UV_VIN_F | Undervoltage threshold for VIN. Device resets. | VIN falling, TPS66120 only. | 2.35 | 2.65 | V | |
VIN falling, TPS66121 only. | 3.79 | 4.30 | V | |||
UVH_VIN | Undervoltage hysteresis for VIN. | 100 | mV | |||
UV_VBUS_R | Undervoltage threshold for VBUS. PPHV switch disabled unitl threshold reached. | VBUS rising | 3.35 | 3.75 | V | |
UV_VBUS_F | Undervoltage threshold for VBUS. PPHV switch disables when threshold reached. | VBUS falling | 3.15 | 3.55 | V | |
UVH_VBUS | Undervoltage hysteresis for VBUS | 200 | mV | |||
OVP_REF | OVP reference voltage. | 0.93 | 1 | 1.07 | V | |
VFWD_DROP_VIN | Forward voltage drop across
VIN to VLDO switch |
IVLDO = 35 mA | 90 | mV | ||
tVIN_STABLE | When VIN is above UV_VIN_R for this duration, VIN is considered valid. If device is being powered by VBUS LDO, it will then switch to VIN supply and VBUS LDO will be disabled. | 5 | 15 | ms |
