6.8 Safety Limiting Values

Safety limiting intends to minimize potential damage to the isolation barrier upon failure of input or output circuitry.

PARAMETER		TEST CONDITIONS	MAX	UNIT
I_S	Safety input, output, or supply current	DW-package, R_θJA = 78.5°C/W, T_J = 150°C, T_A = 25°C, AVDD = DVDD = 5.5 V, see Figure 2	289	mA
I_S	Safety input, output, or supply current	DWV-package, R_θJA =106.5°C/W, T_J = 150°C, T_A = 25°C, AVDD = DVDD = 5.5 V, see Figure 2	213	mA
P_S	Safety input, output, or total power⁽¹⁾	DW-package, R_θJA = 78.5°C/W, T_J = 150°C, T_A = 25°C, see Figure 3	1592	mW
P_S	Safety input, output, or total power⁽¹⁾	DWV-package, R_θJA = 106.5°C/W, T_J = 150°C, T_A = 25°C, see Figure 3	1173	mW
T_S	Maximum safety temperature		150	°C

(1) The maximum safety temperature, T_S, has the same value as the maximum junction temperature, T_J, specified for the device. The I_S and P_S parameters represent the safety current and safety power, respectively. Do not exceed the maximum limits of I_S and P_S. These limits vary with the ambient temperature, T_A.
The junction-to-air thermal resistance, R_θJA, in the Thermal Information table is that of a device installed on a high-K test board for leaded surface-mount packages. Use these equations to calculate the value for each parameter:
T_J = T_A + R_θJA × P, where P is the power dissipated in the device.
T_J(max) = T_S = T_A + R_θJA × P_S, where T_J(max) is the maximum junction temperature.
P_S = I_S × AVDD_max + I_S × DVDD_max, where AVDD_max is the maximum high-side supply voltage and DVDD_max is the maximum controller-side supply voltage.
