6.9 Safety Limiting Values

PARAMETER		TEST CONDITIONS	MAX	UNIT
I_S	Safety input rms current (VDD-VEE)	R_θJA = 52.3 °C/W, V_VIN = 27 V, T_J = 150 °C, T_A = 25 °C, P_OUT = 2 W ⁽¹⁾ ⁽²⁾	150	mA
I_S	Safety input rms current (VDD-VEE)	R_θJA = 52.3 °C/W, V_VIN = 21 V, T_J = 150 °C, T_A = 25 °C, P_OUT = 2 W ⁽¹⁾ ⁽²⁾	200	mA
P_S	Safety power dissipation (input power - output power)	R_θJA = 52.3 °C/W, T_J = 150 °C, T_A = 25 °C ⁽¹⁾ ⁽²⁾	2.39	W
T_S	Safety temperature	⁽¹⁾ ⁽²⁾	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. The maximum limits of I_S and PS should not be exceeded. These limits vary with the ambient temperature, T_A.

(2) 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_qJA × 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 allowed junction temperature. P_S = I_S × V_I, where V_I is the maximum input voltage.
