TPS1HA08CQPWPRQ1 from Texas Instruments, in a HTSSOP-16-EP. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Device ground reference. |
| 2 | SNS | output | Analog sensing output providing load current (ISNSI = IOUT/4600), supply voltage (ISNSV = 0.0867mA/V), or device temperature (dISNST/dT = 0.0112mA/°C) with VSNSclamp = 5.9V and fault indication ISNSFH = 6.0-7.6mA. |
| 3 | LATCH | input | Fault latch control input; high enables auto-retry after fault, low holds fault latch state; voltage range -1 to 5.5V with VIL = 0.8V, VIH = 2V, VIhys = 250mV, and internal 1MΩ pull-down. |
| 4 | EN | input | Switch enable control input, active high; enables output when voltage > 2V, disables when < 0.8V; voltage range -1 to 5.5V with internal 1MΩ pull-down. |
| 5 | ST | output | Open-drain fault status output; pulls low (VOL = 0.4V @ IST = 1mA, ISTleak = 2µA @ VST = 5V) on thermal shutdown, current limit, energy limit, or open-load/short-to-battery detection. |
| 6 | VOUT | output | Power switch output; connects VBB to load when enabled with RON = 8-20mΩ (TJ 25-150°C), supports 10A continuous at 70°C ambient, one of six parallel output nodes; 40V maximum load transient rating. |
| 7 | VOUT | output | Power switch output; connects VBB to load when enabled with RON = 8-20mΩ (TJ 25-150°C), supports 10A continuous at 70°C ambient, one of six parallel output nodes; 40V maximum load transient rating. |
| 8 | VOUT | output | Power switch output; connects VBB to load when enabled with RON = 8-20mΩ (TJ 25-150°C), supports 10A continuous at 70°C ambient, one of six parallel output nodes; 40V maximum load transient rating. |
| 9 | VOUT | output | Power switch output; connects VBB to load when enabled with RON = 8-20mΩ (TJ 25-150°C), supports 10A continuous at 70°C ambient, one of six parallel output nodes; 40V maximum load transient rating. |
| 10 | VOUT | output | Power switch output; connects VBB to load when enabled with RON = 8-20mΩ (TJ 25-150°C), supports 10A continuous at 70°C ambient, one of six parallel output nodes; 40V maximum load transient rating. |
| 11 | VOUT | output | Power switch output; connects VBB to load when enabled with RON = 8-20mΩ (TJ 25-150°C), supports 10A continuous at 70°C ambient, one of six parallel output nodes; 40V maximum load transient rating. |
| 12 | NC | unconnected | No connection pin; may be left floating or tied to ground without affecting device operation. |
| 13 | NC | unconnected | No connection pin; may be left floating or tied to ground without affecting device operation. |
| 14 | SEL1 | input | Diagnostic multiplexer select input 1; low selects load current in SNS output, high selects device temperature; voltage range -1 to 5.5V with VIL = 0.8V, VIH = 2V, VIhys = 250mV, and internal 1MΩ pull-down. |
| 15 | SEL2 | input | Diagnostic multiplexer select input 2; combined with SEL1 to select SNS output between current/temperature (low) and supply voltage (high); voltage range -1 to 5.5V with VIL = 0.8V, VIH = 2V, VIhys = 250mV, and internal 1MΩ pull-down. |
| 16 | DIA_EN | input | Diagnostic enable control input, active high; enables analog sensing output, open-load detection, and short-to-battery detection when high; voltage range -1 to 5.5V with VIL = 0.8V, VIH = 2V, VIhys = 250mV, and internal 1MΩ pull-down. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
