Table 5-1 Pin Functions
PIN TYPE DESCRIPTION
NAME NO.
E/S 4 Input Enable/Shutdown output stage; take E/S low to shut down output
IFLAG 8 Output Current limit flag; active high
ISET 9 Input Current limit set (see Section 8.1)
–IN 6 Input Inverting op amp input
+IN 5 Input Noninverting op amp input
TFLAG 3 Output Thermal overtemperature flag; flag is high when alarmed and device has gone into thermal shutdown
TSENSE 12 Input/Output Temperature sense pin for use with a remote junction temperature sensor
V– 1, 10, 11, 20 Ground –Supply for amplifier, PWR Out, and thermal pad
V– PWR 13, 14 Ground –Supply for power output stage
V+ 2 Power +Supply for signal amplifier
V+ PWR 17, 18, 19 Power +Supply for power output stage
VDIG 7 Power +Supply for digital flag and E/S (referenced to V–).
Valid range is (V–) + 3.0V ≤ VDIG ≤ (V–) + 5.5V.
VOUT 15, 16 Output Output voltage; RO is high impedance when shut down
Pad Thermal Pad — Thermal pad. Connect to V–
