Storage Temperature Range
−65°C to +150°C
ESD Rating (4)
Human Body Model:
2 kV
Machine Model:
200V
(1)
All voltages are with respect to the potential at the GND pin.
(2)
Absolute maximum ratings indicate limits beyond which damage to the device may occur. Electrical characteristic specifications do not
apply when operating the device outside of its rated operating conditions.
(3)
If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(4)
The human body model is a 100 pF capacitor discharged through a 1.5 k
Ω resistor into each pin. The machine model is a 200 pF
capacitor discharged directly into each pin.
Operating Conditions

Junction Temperature (TJ) Range
−40°C to +125°C
Ambient Temperature (TA) Range
−40°C to +85°C
Input Voltage, VIN Pin
2.5V to 5.5V
Cntrl, En1, and En2 Pins
0V to 5.5V
(1)
Absolute maximum ratings indicate limits beyond which damage to the device may occur. Electrical characteristic specifications do not
apply when operating the device outside of its rated operating conditions.
(2)
All voltages are with respect to the potential at the GND pin.
Thermal Properties
(1)
Junction-to-Ambient Thermal Resistance (
θJA)
DSBGA Package
65°C/W
WQFN Package
49°C/W
(1)
The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to-ambient thermal
resistance,
θJA, and the ambient temperature, TA. See Thermal Properties for the thermal resistance. The maximum allowable power
dissipation at any ambient temperature is calculated using: PD(MAX) = (TJ(MAX) – TA)/θJA. Exceeding the maximum allowable power
dissipation will cause excessive die temperature. For more information on this topic, please refer to Application Note 1187: Leadless
Leadframe Package (LLP) and Application Note 1112 (AN1112) for DSBGA chip scale package.
Preliminary Electrical Characteristics
(1) (2)
Limits in standard typeface are for TJ = 25°C. Limits in bold typeface apply over the full operating junction temperature range
(
−40°C ≤ TJ ≤ +125°C). Unless otherwise specified, VIN = 2.5V.
