3 说明

TPS7H2211 是一款单通道电子保险丝（具有附加功能的集成 FET 负载开关），可提供反向电流保护、过压保护和可配置的上升时间，以便更大限度减少浪涌电流（软启动）。此器件包含一个可在 4.5V 至 14V 输入电压范围内运行的 P 沟道 MOSFET，并且支持最大 3.5A 的持续电流。

开关由可与低压控制信号直接连接的打开和关闭输入 (EN) 控制。过压保护和软启动可通过 OVP 和 SS 引脚使用很少的外部组件进行编程。TPS7H2211 采用具有外露散热焊盘的陶瓷和塑料封装，可提高散热性能。QML 5962R1822001VXC 提供了标准微电路图 (SMD)。-SEP 型号 V62/23609 提供了供应商项目图 (VID)。

8 15 GND — Device ground. (2)
12 22 SS I/O Soft start (switch slew rate control). If this functionality is not desired, the SS pin must be left disconnected (floating). In all cases be sure to follow the requirements of Section 9.3.3.
13-16 23-32 VOUT O Switch output. A minimum 10-µF output capacitor is recommended.
5, 9-11 11,14,16,17-21 NC — NC — No connect. These pins are not internally connected. It is recommended to connect these pins to GND to prevent charge buildup; however, these pins can also be left open or tied to any voltage between GND and VIN.
— Thermal Pad — Thermal pad (exposed center pad) for heat dissipation purposes. The thermal pad is internally connected to the seal ring and GND.
— Metal Lid — The lid is internally connected to the thermal pad and GND through the seal ring.

7 Specifications

7.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted); all voltages referenced to GND(1)
MIN MAX UNIT
VIN Input voltage pins –0.5 16 V
VOUT Output voltage pins –0.5 16 V
SS Soft start pin –0.3 16 V
EN, OVP Enable and over voltage protection pins –0.3 7.5 V

(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.

7.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V
Charged-device model (CDM), per ANSI/ESDA/JEDEC specification JS-002(2) ±500
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500-V HBM is possible with the necessary precautions.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250-V CDM is possible with the necessary precautions.
