The IN pin has an internal pull-down resistor. Even if the IN pin is open, the output will not accidentally turn on. Ground pin. Overcurrent detection/protection is IOC(clamp) in the Mask time. If the capacitor and the resistance is not connected to MASK pin, overcurrent protection is IOC(duty). Self-diagnosis detection pin. npn open collector. When Input is “H”(Output on), and Overcurrent or Overtemperature is detected, DIAG becomes low level and it is latched. When input is low level, the state of latch is reseted. Output pin. When a load short-circuit causes an overcurrent (0.8A Min) to flow into a device, output current is limited in order to protect the IC. 2 2012-01-20 TPD1052F Timing Chart Load short-circuit Load short-circuit (Mask time is set) (Mask time is not set) Input voltage VIN Overtemperature Channel temperature Tch detection Output voltage VOUT Mask voltage VMASK Mask time tmask IOC(clamp) IOC(duty) Output current Io Current limited (clamp) Current limited (switching) Shutdown (Latch) Diagnosis voltage VDIAG Normal (Output on) Overcurrent detection (Latch) Overcurrent detection (Latch) Overtemperature detection (Latch) Truth Table Input Signal Output MOSFET State Diagnosis Output H On H L Off H H t ≤ tmask Current limiting (Note) (clamp) t > tmask Current limiting L (Note) (switching) (Latch) Off H L H L Operating State Normal H Off L (Latch) (Latch) Off H Overcurrent (Load short-circuit) Overtemperature ※Note : t is time from the VIN=H input. 3 2012-01-20 TPD1052F Absolute Maximum Ratings (Ta = 25°C) Characteristics Symbol Rating Unit VDS 40 V DC VDD (1) -0.3 to 25 V Pulse VDD (2) 40 (t ≤ 200ms) V Drain-source voltage Supply voltage Input voltage VIN −0.3 to 6 V VDIAG −0.3 to 6 V IO Internally limited A Diagnosis output current IDIAG 5 mA Power dissipation (Note 1a) PD(1) 0.7 Ｗ Power dissipation (Note 1b) PD(2) 0.35 Ｗ Operating temperature Topr −40 to 125 °C Channel temperature Tch 150 °C Storage temperature Tstg −55 to 150 °C Diagnosis output voltage Output current Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges.

Mask time is decided to prevent discharge electricity by switching-mode overcurrent protection that occur by inrush current. To prevent discharge electricity by overcurrent protection(switching) that operate by inrush current, Mask time is used. Overcurrent protection is clamp current in Mask time from VIN=H. Mask time can roughly set at nether expression. ⎛ Rref tmask = −Cmask × Rmask × ln⎜⎜ 1 − R mask ⎝ ⎞ ⎟ ⎟ ⎠ [s] Rref : Internal resistance 110kΩ(typ.) ※ When the Mask time is changed, please change Cmask in the state of Rmask=1MΩ. ※ When overcurrent protection(clamp) is operating, TPD1052F becomes high temperature. Therefore please set Mask time for channel temperature to become 150℃ or less. ※ If you do not use Mask time, please open the MASK pin. 5 2012-01-20 TPD1052F Test Circuit 1 Switching times tr≤0.1μs ①VDD ⑧OUT VOUT VIN tf≤0.1μs 90% 90% 10% ③IN ⑥DIAG 24Ω VOUT 12V ④GND 10% 90% ⑤MASK P.G 10% tOFF tON Application circuit ①VDD VIN ⑧OUT Load tmask IOC(clamp) MPU ③IN ④GND 12V ⑥DIAG MPU ⑤MASK 10kΩ 1MΩ 5V IOUT VOUT Capacitor charge time Mask time 6 2012-01-20 TPD1052F IDD - VDD IDD - Tch 10 10 VDD=12V VIN=0V VIN=0V Output open Output open 8 Supply current IDD[μA] 8 Supply current IDD[μA] Tch=25℃ 6 4 6 4 2 2 0 -80 0 0 4 8 12 16 20 -40 0 80 160 5.0 Tch=25℃ VDD=12V VIN=5V VIN=5V 4.0 Supply current IDD(ON)[mA] Output open 3.0 2.0 1.0 0 4 8 12 16 20 Output open 4.0 3.0 2.0 1.0 0.0 -80 0.0 -40 0 40 80 120 160 Channel temperature Tch[℃] Supply voltage VDD[V] VIH,VIL - VDD VIH,VIL - Tch 2.4 2.4 Tch=25℃ VDD=12V 2.0 1.6 Input voltage VIH,VIL[V] Input voltage VIH,VIL[V] 120 IDD(ON) - Tch IDD(ON) - VDD 5.0 Supply current IDD(ON)[mA] 40 Channel temperature Tch[℃] Supply voltage VDD[V] VIH VIL 1.2 0.8 0.4 0 4 8 12 16 2.0 1.6 1.2 VIL 0.8 0.4 -80 20 VIH -40 0 40 80 120 160 Channel temperature Tch[℃] Supply voltage VDD[V] 7 2012-01-20 TPD1052F IIN(1) - Tch IIN – VIN 200 200 Tch=25℃ VIN=5V 160 Input current IIN(1)[μA] Input current IIN[μA] 160 120 80 40 120 80 40 0 0 2 4 6 0 -80 8 -40 0 80 160 Drain-source ON-resistance RDS(ON)[Ω] 1.0 Tch=25℃ IO=0.5A VIN=5V 0.8 0.6 0.4 0.2 0.0 0 4 8 12 16 VDD=12V IO=0.5A 0.8 VIN=5V 0.6 0.4 0.2 0.0 -80 20 -40 0 40 80 120 160 Channel temperature Tch[℃] Supply voltage VDD[V] VDL - VDD VDL - Tch 0.5 0.5 Tch=25℃ VDD=12V IDIAG=1mA Diagnosis output voltage VDL[V] Diagnosis output voltage VDL[V] 120 RDS(ON) - Tch RDS(ON) - VDD 1.0 Drain-source ON-resistance RDS(ON)[Ω] 40 Channel temperature Tch[℃] Input voltage VIN[V] 0.4 0.3 0.2 0.1 0.0 0 4 8 12 16 IDIAG=1mA 0.4 0.3 0.2 0.1 0.0 -80 20 -40 0 40 80 120 160 Channel temperature Tch[℃] Supply voltage VDD[V] 8 2012-01-20 TPD1052F IOC(clamp) - Tch IOC(clamp) - VDD 4.0 Tch=25℃ Overcurrent detection IOC(clamp)[A] Overcurrent detection IOC(clamp)[A] 4.0 VMASK=L 3.0 2.0 1.0 0.0 0 4 8 12 16 VDD=12V VMASK=L 3.0 2.0 1.0 0.0 -80 20 -40 0 40 80 2.0 VDD=12V Overcurrent detection IOC(duty)[A] Tch=25℃ Overcurrent detection IOC(duty)[A] 160 IOC(duty) - Tch IOC(duty) - VDD 2.0 1.6 1.2 0.8 0.4 0.0 0 4 8 12 16 1.6 1.2 0.8 0.4 0.0 -80 20 -40 0 40 80 120 160 Channel temperature Tch[℃] Supply voltage VDD[V] tON,tOFF - VDD tON,tOFF - Tch 50 50 Tch=25℃ VDD=12V RL=24Ω Switching times tON,tOFF[μs] Switching times tON,tOFF[μs] 120 Channel temperature Tch[℃] Supply voltage VDD[V] 40 30 tOFF 20 10 tON 0 0 4 8 12 16 RL=24Ω 40 30 tOFF 20 10 0 -80 20 tON -40 0 40 80 120 160 Channel temperature Tch[℃] Supply voltage VDD[V] 9 2012-01-20 TPD1052F PD - Ta TOT – VDD 1.0 200 (2) Mount on glass epoxy board (b)(Note 1b) Power dissipation PD[W] 190 180 170 160 0 4 8 12 16 0.8 (1) 0.6 0.4 20 (2) 0.2 0.0 -40 150 0 40 80 120 160 Ambient temperature Ta[℃] Supply voltage VDD[V] rth - tw 1000 (1) Mount on glass epoxy board (a)(Note 1a) (2) (2) Mount on glass epoxy board (b)(Note 1b) Thermal resistance rth[℃/W] Overtemperature detection TOT[℃] (1) Mount on glass epoxy board (a)(Note 1a) (1) 100 10 1 0.1 0.001 Single pulse 0.01 0.1 1 10 100 1000 Pulse width tw[s] 10 2012-01-20 TPD1052F Package Dimensions Unit; mm 0.33±0.05 A 2.4±0.1 2.8±0.1 0.05 M B 0.17±0.02 0.05 M A S +0.1 0.025 0.28 -0.11 S 1.12 0.8±0.05 2.9±0.1 B -0.11 0.65 0.28 +0.1 0.475 +0.13 1.12 +0.13 -0.12 -0.12 0.33±0.05 Weight：0.017g (typ.) 11 2012-01-20 TPD1052F RESTRICTIONS ON PRODUCT USE • Toshiba Corporation, and its subsidiaries and affiliates (collectively “TOSHIBA”), reserve the right to make changes to the information in this document, and related hardware, software and systems (collectively “Product”) without notice. • This document and any information herein may not be reproduced without prior written permission from TOSHIBA.
