TPS1HTC30-Q1 Pin Functional Groups
Source: TI TPS1HTC30-Q1 datasheet, Section 5 “Pin Configuration and Functions” for PWP / HTSSOP-14 package.
Each physical pin is assigned to exactly one functional group below. Repeated electrical functions such as VS and VOUT are grouped together, but no pin number is duplicated across groups.

Table

Functional GroupPinsPin NamesSuggested SectionSuggested Pin GroupSuggested Flux Pin TypeNotes
Power Input / Supply12, 13, 14VSPowerVS / PowerPower InMain device supply input pins. Group all three together.
Power Output / Load Output8, 9, 10VOUTOutput / SignalVOUT / OutputPower OutHigh-side switch output pins to the load. Group all three together.
Ground / Thermal Return1, Thermal PadGND, GND thermal padGroundGND / GroundGroundDevice ground and exposed thermal pad. The thermal pad is internally shorted to ground and should be grouped with ground, not as a separate signal function.
Logic / Control Inputs2, 3, 5, 7EN, DIAG_EN, LATCH, ILIMControlControlInputEnable, diagnostics enable, thermal latch behavior select, and adjustable current-limit configuration.
Diagnostic Outputs4, 6FAULT, SNSSignal / DiagnosticDiagnosticOutputFAULT is an open-drain fault output; SNS is the current-sense / diagnostic analog output.
No Connect11NCNo ConnectNCNot ConnectedNo internal connection; do not reuse this pin in another group.
  • Power Input: VS pins 12, 13, 14
  • Vout / Load Output: VOUT pins 8, 9, 10
  • Gnd: GND pin 1 and exposed thermal pad
  • Control: EN pin 2, DIAG_EN pin 3, LATCH pin 5, ILIM pin 7
  • Diagnostics: FAULT pin 4, SNS pin 6
  • No Connect: NC pin 11
Notes
  • Do not put the same physical pin into both “Power” and “Gnd”; for this part, I recommend keeping supply input, output, and ground as separate functional groups because they serve different electrical roles.
  • If Flux requires a broader Section field, use: Power for VS, Signal/Output for VOUT, Ground for GND/thermal pad, Control for EN/DIAG_EN/LATCH/ILIM, Signal/Diagnostic for FAULT/SNS, and No Connect for NC.
  • If Flux requires a Pin Group field, use the specific names above: VS, VOUT, GND, Control, Diagnostic, NC.

  • Recommended Non-Duplicated Grouping

Automotive, 60-V, 6-A, 30-mΩ, one-channel smart high-side switch with adjustable current limit
TPS1HTC30-Q1 is a single-channel, smart high-side switch, with integrated NMOS power FET and charge pump, designed to meet the requirements of 24-V automotive battery systems. The low RON(30 mΩ) minimizes device power dissipation driving a wide range of output load current up to 6-A DC, and the 60- V DC operating range improves system robustness. The device integrates protection features such as thermal shutdown, output clamp, and current limit. These features improve system robustness during fault events such as short circuit. TPS1HTC30-Q1 implements an adjustable current limiting circuit that improves the reliability of the system by reducing inrush current when driving large capacitive loads and minimizing overload current. The device also provides an accurate load current sense that allows for improved load diagnostics such as overload and open-load detection enabling better predictive maintenance. TPS1HTC30-Q1 is available in a small 14-pin, 4.40- mm × 5.0-mm HTSSOP leaded package with 0.65- mm pin pitch minimizing the PCB footprint.
• Single-channel smart high-side power switch for 24-V automotive systems with full diagnostics • Wide operating voltage range: 6 V to 60 V – OVP protection: 66 V • Low RON: 30-mΩ typical, 55-mΩ maximum • Low standby current: < 0.5 µA • Low quiescent current (Iq): < 2 mA • Improve system level reliability through adjustable current limiting – Current limit: 2 A –16 A • Accurate current sensing: ±4% at 1 A • Protection – Overload and short-circuit protection – Integrated inductive discharge clamp – Undervoltage lockout (UVLO) protection – Loss of GND, loss of supply protection – Reverse battery protection with external components • Diagnostics – On and off state output open-load and short-tobattery detection – Overload and short to ground detection – Absolute and relative thermal shutdown detection • Functional Safety-Capable – Documentation available to aid functional safety system design • Operating junction temperature: –40 to 125°C • Input control: 1.8-V, 3.3-V and 5-V logic compatible • Integrated fault sense voltage scaling for ADC protection • Qualifications – AEC-Q100 qualified for automotive applications • Temperature grade 1: –40°C to +125°C, TA • 14-pin thermally-enhanced TSSOP package TPS1HTC30AQPWPRQ1
